CruiseYou know that moment when the ship finally pulls away and San Francisco starts shrinking behind you? The skyline gets hazy, the Golden Gate sits low on the horizon & suddenly it hits you: you’re not doing a “regular—cruise.” You’re crossing the Pacific.
An 18-day Transpacific cruise from San Francisco is the kind of trip people talk about for years. It’s part ocean adventure, part floating resort, and part culture-hop—usually with Hawaii in the first half and Japan (sometimes more) in the second.
But let’s be honest: the big question isn’t only “Where do we go?” It’s also, “How much will this actually cost once we add tips, tours, Wi-Fi, and those random onboard temptations?”
So here’s a practical, human guide—bucket-list ports, what’s truly worth doing, and a realistic budget you can plan around.
Why an 18-day Transpacific cruise from San Francisco feels different
A normal cruise is a quick hit: port, port, port, fly home. A transpacific sailing moves slower. And that’s the magic.
You get:
- Proper sea days where the ship becomes the destination
- Enough time to reset your body clock and settle into a rhythm
- A route that often combines Hawaii + Japan in one trip (which feels unreal when you say it out loud)
Also, these sailings are often repositioning itineraries. That can mean better value per day compared to peak-season Caribbean or Alaska weeks—if you stay smart with add-ons.
When to go: timing that makes sense
Most Transpacific cruises from San Francisco show up in spring and fall. That’s when ships move between seasonal routes.
What to expect:
- Cooler starts leaving San Francisco (especially evenings on deck)
- Warmer, beachy weather in Hawaii
- Crisp, comfortable days once you reach Japan (depending on month)
So yeah… pack like a layered person. Even if you never pack like a layered person.
A “typical” 18-day routing (what you’ll usually see)
Itineraries change a lot by cruise line and year, but the structure often looks like this:
- Day 1: Depart San Francisco
- Days 2–5: Sea days (you’ll feel the Pacific size)
- Days 6–8: Hawaii ports (often Honolulu + one or two islands)
- Days 9–13: More sea days (this is the deep-ocean stretch)
- Days 14–18: Japan ports + arrival/disembark (often Yokohama/Tokyo area)
Sometimes you’ll see added stops like Busan or extra Japan ports. Still, Hawaii + Japan is the classic combo.
Bucket-list ports (and what’s actually worth your time)
1) Honolulu (Oahu) — the “choose-your-own-adventure” port
Honolulu is easy and flexible, which is why people love it. You can go heavy on history, keep it beachy, or mix both.
Top picks:
- Pearl—Harbor
- Waikiki for a classic first-time Hawaii—vibe
- Diamond Head if you’re up for an early hike with a payoff view
Realistic tip: Don’t try to do everything in one day. Pick two main things, then leave room to just be there.
2) Maui (Kahului) — scenic overload (in the best way)
Maui is the “wow, this looks fake” stop.
Popular options:
- Road to Hana (gorgeous, long, and not for everyone)
- Haleakalā (sunrise is famous, but planning matters)
- Simple beach day + food hunt (honestly, underrated)
Honest warning: Road to Hana can feel like a marathon. If you hate long drives or get motion sick, don’t force it.
3) Hilo (Big Island) — rainforest energy + volcano vibes
Hilo feels greener, quieter & moodier than the resorty side of Hawaii. If your schedule works out, Hawai‘i Volcanoes National—Park is the headliner.
Other good choices:
- Waterfalls
- Tropical gardens
- Short scenic stops that don’t drain you
Budget note: This can be a solid DIY day if you’re careful with transport.
The “long sea stretch” in the middle (how to not lose your mind)
After Hawaii, you’ll likely have several sea days in a row. Some people love this part. Others don’t understand it.
Here’s how to make it the best part:
- Start your morning with something simple: coffee + a deck walk
- Book one treat for the middle: spa pass, specialty dining, or a class
- Use sea days to catch up on sleep (you’re not “wasting time,” you’re recovering)
- Don’t schedule every hour. Leave room for nothing.
On an 18-day sailing, pacing—matters. If you go too hard early, you’ll feel it later.
Japan: the ports that feel like stepping into a movie
4) Yokohama (Tokyo gateway) — big-city energy, fast
Many cruises end or overnight around Yokohama, which makes Tokyo doable.
Good “first Japan” plans:
- Asakusa (Sensō-ji + old streets)
- Shibuya (crossing, shopping, city buzz)
- Shinjuku (lights, skyline, food)
Reality check: Tokyo isn’t one place—it’s a bunch of cities stacked together. Pick a few neighborhoods and commit. You’ll enjoy it more.
5) Shimizu (Mt. Fuji area) — postcard potential
When Mt. Fuji shows up in the distance, it’s a core memory. The trick is: Fuji visibility depends on weather.
Options people love:
- Fuji viewpoints
- Tea farms and local scenery
- Coastal photo stops
Backup plan tip: Choose an excursion you’ll enjoy even if Fuji hides behind clouds.
6) Osaka / Kobe — food, fun, and great day trips
Osaka is loud in the best way—friendly, tasty & energetic.
Ideas:
- Street—food crawl
- Day trip to Kyoto for temples & old—streets
- Kobe waterfront if you want a calmer day
Be real with yourself: Kyoto in a single day is doable, but it’s a full—day. If crowds stress you out, stay local and eat your way through Osaka instead.
A realistic budget (USD): what people actually spend
Cruise pricing changes constantly, so think in ranges. This is the safest—way to plan.

| Cruise—fare | $1,800 – $3,200 | Best value if you don’t need a view |
| Cruise—fare | $2,400 – $4,200 | More light, still sensible |
| Cruise fare (Balcony) | $3,200 – $6,000+ | Sea days feel premium here |
| Port fees & taxes | $250 – $500 | Depends on itinerary |
| Gratuities (18 days) | $288 – $360 | Often ~$16–$20/day |
| Shore tours | $300 – $1,200 | DIY vs guided changes everything |
| Drinks (no package) | $150 – $600 | Coffee + cocktails add up fast |
| Wi-Fi | $100 – $400 | Plan type + cruise line |
| Specialty dining | $0 – $300 | Optional, but tempting |
| Insurance | $80 – $250 | Age/coverage affects price |
| Flights (varies widely) | $500 – $1,800 | Depends on where you start/end |
| Hotel pre/post cruise | $150 – $600 | 1–2 nights is smart |
What most travelers land on
- Value style (inside + DIY ports): ~$3,200 – $4,800 total
- Comfort style (oceanview + mixed tours): ~$4,800 – $7,200 total
- Treat-yourself (balcony + packages + tours): ~$7,000 – $11,000+ total
How to save money without making the trip feel “cheap”
- Book early for the cabin you want, then watch for onboard credit deals
- Don’t buy a drink package unless you’ll truly use it (do the math honestly)
- Mix paid excursions with DIY days (1–2 “big” tours is usually enough)
- Arrive in San Francisco early (missing a ship is expensive stress)
- Pack essentials like meds and sunscreen—ship prices can be painful
What to pack for a Transpacific (the stuff people forget)
- Layers for sea days (wind can sneak up on you)
- Comfortable walking shoes (Japan is a walking country)
- Motion-sickness plan (even if you swear you don’t get seasick)
- A small day bag for ports
- A cruise-safe power strip (non-surge) and adapters
