I haven't sent my kids to any of the clubs yet, but I did call for information about Camp 'Lil Rock (at HRH).
It cost $10/hour for the first child & $8/hour for each addt'l child. Dinner is provided if they are there around 7:00pm, but it's at an addt'l cost ($10). There hours are 5pm-11:30pm during the week and from 5pm-Midnight on weekends.
I did call once before and was told on Friday's and Saturday's Camp 'Lil Rock was open from 10:30am til Midnight, but you may want to check first.
As far as activities and such, I have no idea what it includes.
If you want to do the search, maybe you should use the Kids Clubs names for the hotel you'd like. I know HRH is Camp Lil Rock & PBH is Campo Portofino. I'm not sure what RPR is called.
Hope this helps!
