You'll love the GF, especially the lobby/atrium.
We are very infrequent visitors to DW, only three trips in the past thirty years. Yet our "second" trip, in 1993, was memorable because we stayed at the GF. Upon check in we were informed that the outer building where we reserved was overbooked, so they were moving us to the main building - club level, no less (back then we weren't sure what that even meant).
Now that was a great experience. Club level at that time at the GF was like having a restaurant move into the CL lobby four times a day. I remember the evening sweets were spectacular, huge variety of items of high quality. I believe the breakfasts even had hot foods like scrambled eggs and French toast. The evening spread was literally a full meal, if you wanted it to be that. It was nothing like the club levels at hotels today regardless of where you stay - it was far superior to anywhere else we have stayed.
The other two trips were to the Poly way back in 1986, and the Yacht Club (club level) in 1999. Since then we've pretty much become a Universal family and have stayed at the Hard Rock (club) and the Portofino Bay (club) several times, and this year we're doing the Royal Pacific club. But none of them have ever come close to that stay at the GF club level in terms of quality and luxury.
