Hi There,
We have stayed at this resort a couple of times............ They have a swimming pool which is pretty good but its certainly not a water resort.
Sea World is opening a brand new water resort in the Spring I,d plump to go there..... Once you get in they also do the next visit free when you validate your ticket inside the entrance gates.

Details of on site facilities, including splash lagoon here http://www.orangelake.com/tour_our_resort/home.html. We are going to OLCC North Village for 4 weeks in summer 2009 (timeshare exchange)
