Is there enough for tweens (3 boys) to do on RC Enchantment of the Sea?

[GoGo 2 Three Boys]

We are in the process of booking a cruise for this summer. We will be traveling with our daughter's family which includes three boys, ages 12, 12, and 11. We want to cruise out of Galveston (we live in Texas) and so our options are a bit limited. We are looking at a 5-night cruise on Royal Carribean Enchantment of the Seas. Has anyone here cruised with tween-age kids on this ship? It doesn't appear that there's much for them to do. We'd love a big water park onboard but those ships don't cruise from Galveston? Any suggestions? This will be our first time cruising with our whole family and I want to make sure the boys have a great time. Thanks for any help you can give me!

Carnival Dream is doing 5-day cruises out of Galveston, and it has water slides.  If you move up to 7 day cruise, RCI Liberty and Carnival Vista both have a ton of activities for tweens.

The stuff on a cruise ship cannot be described as a 'water park" by any stretch of imagination.  Some ships have slides....good for a couple trips down...I wouldn't book a cruise for the slides!
