I have not used the day care facilities at any of these gyms, so I don't know how good they are, but I know they exist. In general the gyms are good and offer a variety of classes. I really like the yoga class with Astra at Northgate Express.
I have been a member for 10 years and have never had the price go up on my membership. However, since I joined before 24 hour fitness existed (it was Family Fitness back then) I have an "active" membership and can't use the "sport" clubs. I tried to upgrade but it was way to expensive, and definetly did not seem worth it.
Check out a club near you and see what they have to offer.
