The room is very, very nice and big, the pool is not too big though, but it was okay. However, it is situated on the G/F and you have to pass part of the lobby to get to it. I would recommend you to go Westin or the Mandarin if you want to stay somewhere nice in Macau with bigger pools.
BTW, one of the taxi driver recommended us to go to this local park. They have small 電動 cars for kids to play at MOP 5 for 15 mins, and also slides beside it. I think only local ppl knows of this place - all locals when we were there. Zachary had a lot of fun!
