RTW, when are you going to be there?
As I noted in the other thread on GC's:
I am potentially staying at the GH HK next weekend (12/3-12/8). Given that the hotel is very full during this period, I confirmed myself into a GC, City View King.
So, they got me to pay the extra rate for a GC room, but I didn't pay the extra $50 for a Harbor View room vs. a City View room, but hopefully -- especially since I've stayed at this hotel already 3x this year -- I will AT LEAST get a Harbor View upgrade...although the fact that the hotel is full is a concern.
My check in time would be about 6PM.
Hopefully, I will be going on this trip and will report back on check-in/upgrade experience.
