I just came back from 長隆酒店, there is no 三腳插蘇 but you can ask it to give you "tor ban". We requested one & use it to charge mobile phone & the battery for video camera. :mrgreen:
長隆 swimming pool is not very special, my son is ~ 90 cm height & cannot stand in the pool, so you better bring/buy the 水泡 otherwise you need to hold your son.
If next time you go to 祈福, sure your son will enjoy very much in the water world ($20/entry for resident). My son likes to walk, play the slide by himself very much. (no need to bring 水泡) He spends more than 1 hr there. Really worth to go.
