I have never been there, but I have seen a couple reviews on this in a past post - here is the first:
Here's a little description of the hotel: Cape Codder
They have great children's activies...bonefire, movies in addition to the pool area. Kids just love it. I've had many friends that have had birthday parties for thier children there. My DIL and her family stayed there with 3 children ages 3, 5 & 7 and just loved it. Went swimming during the day, ate dinner, went to the bonefire and back into the pool. so yes, I'm sure you'll like it. It is a nice hotel.

p.s. They have a great spa too, even with spa programs for kids, men, women & even Mommies to be!!!
the other review was this:
The CapeCodder Resort is not a water park, but rather a wave pool. I live very nearby and have been to a few birthday parties and spent one night there last winter during our "blizzard" just to get out of the house. I paid $99 and thought it was barely worth that. Like I said, it's just a wave pool with a few slides (hot tub for parents was fairly nice though). BIggest problem with how hot and steamy it was in the pool area, lack of chairs/seats for those not in the water, rules about food/drinks, mildew or moldy rooms and carpets, horrible service and food at the Hearth N' Kettle on premises (and we like HnK normally). If you are desperate to get away like we were without any real traveling and for under $100, maybe... Otherwise, I'd pick a different place. Just my honest opinion.
So.... 2 totally different opinions
hope this helps some.
