I have 5 kids, and have put them in kids clubs on many vacations, heck I use to belong to gyms with free childcare just for a break (SAHM). However, parents really should make sure they can be reached and get to the kids club in a reasonable amount of time, in case the child is sick (I’ve had that happen twice), has an accident, or just wants to leave (this isn’t paid daycare). I could see leaving older teens if they really didn’t want yo get off of the ship (my kids always wanted to get off).
