I love GG. I agree with everything stated above. But you have to be prepared for the GG.
The rooms are not big, as a matter of fact, they are tiny. However, if you are someone that just needs a spot to rest and shower, this is it. The renovation was long overdue and they did a good job with the updates. The bathrooms are small and nothing fancy. FYI - if you are 2 in a room and you dont want to hear whats going on in the bathroom, you will need to spend some time in the casino. You can ask for a room facing Main Street if you think the FSE noise will be an issue (its never bothered me, mainly because I dont go to bed till long after the shows are over).
You may want to check in on the the Suites/Penthouse. Ive never actually seen it, but if you need the room and have the cash, is a great option.
The other element about GG I love is the size/location. You can leave your room and be at a table in 3 mins. The cocktail service is swift, DuPars has a GREAT breakfast and since they are a smaller property, comps are easy to get. Finally, if you are not feeling it, you can leave your table/slot and be at another spot in 5 mins.
I would recommend GG and if you don't like it, then you've only lost 1 night.
If you go, let us know how it was
