I live in Ruxin Hotel. Go to West Rail and sit at Exit D1 of Honghong Terminus. Walk along the corridor and you'll be there soon. Wednesday is free, but there will be a lot of people queuing in. So I chose to give money in. Adults pay HK$25 and children from 11 to 3 are half-price. The facilities inside are all right for a whole day. And with the internet, the children play by themselves, so I can sit and surf the internet. If you are hungry and want to eat wild, you can talk to the staff, then go out to the lobby on the first floor and eat before you go in and play. However, some people are really bad, ignoring the rules. You can play until 9 p.m. on Saturdays and Sundays. If you try everything and see the scientific truth, the fourth floor can really play for a whole day. Mirror world and children world are the most fun. My son stayed the longest.
