I've played at Fanpekka several times. The new area recently had a sandbox and rainbow slider. The area is huge, so the kids can enjoy everything they want. From playing in the sand, going down the slide, playing high ropes, playing ball pits, building houses, playing role-play, and even joining in on games with their older siblings.
Parents don't have to worry about getting tired because there are plenty of bean bags and rest areas to relax. There are even massage chairs available. Wow, this is so much fun for those who accompany their kids playing inside, it's so relaxing too 😆
