Princess does a lot of things beautifully. Fresh pasta made to order, itineraries that go places the megaships cannot, some of the best service-per-dollar in mainstream cruising, and a passenger base that thinks a big night is the 7:30 production show. Multigenerational families adore it, and the grandparents in your travel party will lobby for it.
Which is exactly why it needs a clear-eyed toddler review, because the line’s strengths and a two-year-old’s needs barely overlap.
The Under-3 Reality
Princess’s youth program, Camp Discovery, welcomes children from 6 months old — but everyone under 3 must be accompanied by a parent the entire time. There is no drop-off nursery anywhere in the fleet. No hourly babysitting room, no Royal Babies & Tots equivalent, no “it’s a small world” nursery. If your child is under 3, you are with them for every hour of the cruise, full stop.
From age 3 (potty trained), Camp Discovery becomes a genuine drop-off club, included in the fare, with well-run age groups. The flip at three is as stark as Norwegian’s: one birthday changes the entire vacation.
The Water Situation
Standard rules apply and there is no carve-out: children in diapers or swim diapers are not permitted in Princess pools, and the fleet has no dedicated diaper-friendly splash zones. A not-yet-potty-trained toddler on a Princess ship does not get wet. Combined with the no-nursery policy, that is both of our two questions that matter answered with a no.
What Princess Does Offer a Family
Fairness requires the other side of the ledger. Princess’s OceanNow system delivers food and drinks to wherever you are sitting, which parents of napping-in-the-stroller children rate as quietly life-changing. The MedallionClass tracking means you can find your spouse and kid on a deck map instead of texting into the void. Cabins are quiet, the pace is gentle, and there is no casino-adjacent chaos between you and dinner.
And the itineraries are the real argument: Alaska with glaciers, longer Caribbean routes, Mediterranean runs that skip nothing. If the trip is really about the place, Princess routinely gets you there better than the family-focused lines. Our Disney Wonder Alaska guide covers the family-first way to do Alaska; Princess is what the retired couple next to you at the glacier chose, at two-thirds the price.
What It Costs
Fares sit mid-pack: above MSC and Carnival, below Disney, in Royal Caribbean territory. Gratuities run $18.00 per person per day for standard cabins at the published 2026 rate, all ages. Model your version in the cruise cost calculator. The Princess Plus and Premier bundles (drinks, wifi, gratuities packaged) pencil out more often than most line bundles, for the adults at least.
Bottom Line
Book Princess when the youngest member of your party is 3 and potty trained, and it quietly becomes one of the best value-for-calm propositions afloat. Book it with a 20-month-old and you have paid mid-tier money to provide all the childcare yourself on a ship where your kid cannot enter the pool. The line is not doing anything wrong; it is simply built for a different chapter than the one you are in.
If the under-3 window is now, the honest shortlist remains Disney on any ship or Royal Caribbean on the right one — and the full six-line comparison shows exactly why the field narrows to two.
