This is a pricey outfit (~240 USD for a double) with pretty insane lobby displays that are worth checking out. Price of double room came with pre-loaded credits worth about 50 USD. Double rooms are spacious, and come with a nice bathroom that has a separate toilet, rain shower, and tub.
The facilities in Galaxy Hotel are definitely fancy. They have a schedule of things to do throughout the day, including Yoga classes, and times when the wave pool is in operation for those who want to surf or boogie board. They have about three large pool areas (and jacuzzis), complete with fake beaches and sunken bars. Do bring your room keycard with you if you wish to access the recreational facilities - they control entry.
Dining is expensive and can be quite a hassle during dinner time. During the peak dinner time (6-8 pm), most of the dining options had lines that involved at least 30 mins waits. So book in advance, or be prepared to eat at MacDonald's.
