Cons-
1- You can not take your MOBILE inside for photography. so plz go with Compact camera if you want to take photos inside
2- Red shoe n blue shoe matters , means there in a climbing mountain wall inside on which some days only red shoes are allowed n some day blue. this shoes u will get on entry. so u can miss chance to climb on mountain wall inside.
3-Has only one slow slide .
4-Area is small
5-Due to Extreme cold you get only 1 hour entry .but its hard to stay for one hour inside.
