August 2015 - 7 Night Western Caribbean (Galveston Roundtrip) Cruise on Navigator of the Seas
The Teen programs were somewhat limited. Although our older teen liked it, it was more of a function of hanging out with other teens than actually "doing stuff". Similar with our other younger teen, but she liked it less.
On the other hand, the Toddler program was terrible. The 3-5 year old program had some strange restrictions / limitations: the children couldn't bring in food or drink, the children must be able to use the toilet 100% themselves (no help whatsoever), there was no kiddie pool, and the ratio was something like15 to 1. We basically couldn't leave our 3 year old for more than 1 hour!
On the on communication requires you to buy an expensive per phone internet data plan and / or "Roam" with your carrier (very expensive). Other ships have cordless phones or inexpensive apps that can be used. This should be addressed.
