one more advice, when u go to USS get the express pass, trust me it's gonna be worth it unless you're going on a non-peak season where u expect very less people.
when i went, i had to queue up to an hour for certain rides, wasted a lot of time and didn't manage to go around much.

*also, please purchase your entry tickets online first - seems USS have limited entry tickets per day. a lot of tourists didn't manage to get in because of that too. tickets gets sold out before lunch time when i got them
