I'd second the recommendation for tumble time - easy to deal with, reliable and excellent. http://www.tumbletimedubai.com/
Depends what type of party you want but Tina at Splash n bounce is really good too and you can't beat Me&Riley
Cheeky monkey are excellent and keep the kids entertained brilliantly. Tumble Time not so good in my opinion - Dont seem to be able to pitch the games for the right age group.
