N.T.
My daughter is two, and we have been going to both play areas several times a week with no problems.
I do Strollerfit at Stonebriar 3x/wk, and we go to the play area after, and then some evening, we go to Willowbend since it is closer to my home and it is a great evening activity when the weather is really cold/rainy, etc. I have no complaints.
Also, I have been kicked out of the play area on many occasioons for them to clean it at like 6p.
I really can't complain about the illness factor that you all report. I know that some women in my playgroup have mentioned concerns about their kiddos getting sick and having just been to the play area. But we have not had anything like that.
