I am afraid most places are shut during summer. Even aspire gym stop their activities during summer holiday. THe only place i know that you can entertain the kids is by sending them to summer school / summer camp. Little Angels accepting kids till 10 yrs old, while busy bees only take the kids up to 5 yrs old, Star Fish Lane take the kids up till 8 yrs old.

I have post the details about this nurseries opening summer program for kiddies few weeks back. Try to do search on this forum i think you will find it no problem.
