It looked very kid friendly...there are two pools that we saw...yes one of them had a slide...not sure about the other one. The one we were looking at looked like it was made for kids with a big, and I mean big octupus fountain, and other very large sea animals...very cool.
I would say $200 per night is a bargain...considering they get way more than that for the deluxe resorts on disney property...and this resort has a lot to offer...many, many different restaurants...two pool areas, castle in the middle, paths for kids to explore,.....the inside looks like you are outside...it is very cool.
There were families all over the place when we were there...we sat for about an hour eating lunch...everyone looked like they were having a great time.
