The kids club is available to everyone at Mayan Palace, Grand Mayan, Grand Bliss, and Grand Luxxe. There will be a list of activities are free but, if you want kids to be there for several hours and have lunch while you go somewhere, you have to pay. The prices are listed at the Kids Club. When we were in Acapulco when our grandson was 8, they had organized activities each day and all kids could join in. There was a gal who came around looking for kids to participate. One time we did pay for him to participate all day so we could go into town and do some shopping.
Our grandson loves the Kids Club. The one in Acapulco was his favorite.
