I chose this ship because I love Christmas. But There is not Baby Splash Zone....I saw older babies with swim diaper in the pool and men (lifesaver) don't complain about older babies that worn swim diaper. The lifesaver allowed these children in the pool.
The salesperson from Royal Caribbean could advice before you take a decision for booking. I suggested you choose some ship that offer Baby Splash Zone (swim diaper is allowed).
The entertainment of the Oasis the Seas is much better than Jewel of the Seas. Improve shows at theatre for Christmas to children (for example "Home alone")... Movies at 7pm or 8pm... Some movies started 10pm and I think that too late for parents.... Comedy movies (Christmas) that involves everybody in the family.
I got a portable crib to my baby....and everything is clean...
