I just came back at Wednesay, let me share my point of view
1. you can book return ticket once u arrive hotel, very lightly chance u can't book same shipment.
2. check in as early as u can, because everywhere have to wait, check in, buy ticket, always seen many ppl line up.
I would recommand before noon, even they can't give you the room at that time, but you could leave the laugge and eat, walk arond at 3/f(food court & shopping acrade) it already kill you two hrs.
3. must try Godola, nice experience.
some package inclusive, never forget to bring the DC, I forgot so have to buy those photo taken by the offical camera man,$190 1x8R,1x5R.
5. , wake up earlier in the next morning and go to swim/breakfast, you decide what first la.....but I can tell you I went to cafe deco at first day at 9:xx, already over 1/20 ppl at the line..another reaturant-blue frog ,also have to wait, finally pick the last one- fogo sohba, which I recomend u try, free for childern under 5.
