I love the Tri City Court Club. It has everything you need in a fitness center, including activities for the kids. The price is a little more expensive than other places, but you get what you pay for, and you get a LOT at the TCCC. There is an indoor pool, a rock wall, tennis/raquetball courts, circuit training, daycare, aerobics, free weights and a fitness center...the works!
The daycare prices are very reasonable. I like that I can pay a couple dollars for both of my kids for the hour or so that I am in the gym.
