We took our kids to Let's Play last weekend for the first time, for a birthday party, and we won't be going back. Sure, it's huge and I guess there's a lot to keep kids busy - but the place was a zoo with little to no supervision (neither parents nor staff seemed to care what kids were doing), the party set-up was disorganized, staff were often nowhere to be found and the whole place seemed dirty.
I know how expensive it is to book a party there and I wouldn't pay a quarter of that!
