I belong to a "fancy" gym. I get a good deal through my work - no enrollment fee, $60/mo. I can do daycare for $7 per kid per visit (up to 2.5 hrs). My gym has two locations and the facilities and equipment are great. Two of the locations have indoor pools (lap pool, activity pool, and warm water pool) and jacuzzis, one has an outdoor roofdeck pool. Multiple group class rooms, dedicated spinning rooms, Pilates reformers, etc. Nice locker/shower facilities, etc. Almost all group fitness classes are inlcuded, and run the gamut from yoga, step, spin, water aerobics, spin, cross training, etc.
They're about to open a third location within walking distance of my house, and we'll probably go up to a family membership at that point, which is about 2-3x more, but includes unlimited childcare plus DH can start going to the gym, too.
