Beijing hotel with children's pool

We're coming to Beijing for the weekend.  Can anyone suggest a good family hotel with children's swimming pool.  Just after a pool not so deep.

Location can be anywhere since we are just going to the zoo. 

Many thanks!

There is a hotel called Guang Ming Hotel and behind it there are many houses. You can go there and go to the pool and say that you are a guest of house ............. (does not really matter)
