I bought vouchers from Groupon for 2 hours of play during weekends. It costs $12.50 per child (usual $25). The indoor playground is narrow and crowded, we didn’t really like it. The playing facilities are four storey high. Parents need to climb up and down with the younger kids, which is rather tiring. We prefer those indoor playgrounds that are more spacious, rather than high. However, the kids still enjoyed themselves as usual, but I guess we won’t be going back to the indoor playground anymore.
