Not sure when you're going, so I can't say for sure, but we were there the week before Christmas, and there were LOTS of activities! Our "kids" were 19 and 23, so they weren't particularly interested, but I would have been really pleased if I had younger children.
All of the buildings at CPGV surround the two pools, mini golf (nothing fancy), activity building, and playground. They had a long list of activities going on while we were there (games, arts & crafts, mini golf tournament, etc.).
I would ask for a condo facing the pools, etc. You'll be right in the middle of everything. We never had a problem with noise though. Now and then you would hear somebody but hardly ever.
The volcano pool is a short walk away at CPR, and I think they have an arcade over there too. You can, of course, use the facilities at either section of the property.
