yes, i just moved here not long ago and i was in a similar situation. i tried the 24hour fitness at 119th and metcalf...DO NOT USE THAT PLACE!!! they don't pay attention to the kids, left my little one in a poopy diaper for at least an hour. plus, it's not that clean, and you have to wait to get in a lot. so i quit there and joined praiire life. i like it so far...my kids really enjoy it. the staff interacts with the kids, and they watch them well. we have a month-to-month membership that i can cancel with 30 days notice. we pay about 125 a month, but i have 4 kids i pay for...so it is a bit more expensive than if tyou just have 1 or 2 kids.
but did you know that Lifetime fitness is opening in october on 135th and metcalf??? it may be a farther drive for you, so you may not be interested. but pricewise, i think it's about the same as prairie life. but of course they may be running special deals as it gets closer to their opening because they are new. you'd have to check. i belonged to lifetime in illinois and i totally loved it there...and my kids did too. i became quite friendly with the child center staff, and they were always top notch, and i swear, they almost loved my kids as much as i do. well, ok, that's a little strong, but you know what i mean.
but anyway, one thing about praiire life, is that the kids membership fee gets them free swimming lessons, and that's cool. but, if you buy the 12 month membership and you make any changes to it, it starts your 12 months all over again. so if in say, 4 months you add your hubby or another child, when you do, you start all over with the 12 months from that point.
hope that helps.
