I only have experience in the Lifetime Fitness is Carrollton and from what I can see they seem nice and pretty clean. I am VERY particular on where I leave my son especially because he has gotten sick a lot when he was younger from daycares and he also had separation/stranger anxiety and still does but not as bad so in that note I feel comfortable enough for my 17 month old to stay there for an hr or two if needed. I took my son there to see how he would do and so I can get a feel of it and I stayed there w/him and he had fun. I took him there once he cried a little but he was having fun playing.
I hope this helps but if you talk to the the childcare and let them know any concerns you might have they will let you stay their w/your daughter for evaluation and so you can decide.
Good Luck!
