Usually when the word "Lodge" is used in conjunction with the GF, it means the resort's other buildings, not its Main Building.
If you
click here, you will see the GF room rates for 2005. Compare what you were quoted with what is listed on this webpage (these rates are non-discounted and do not include tax).
If you
click here, you will find out information about the Grand Floridian's rooms, including its concierge rooms and what access they have to the lounges.
If you have booked a concierge room in the Main Building, you will have access to its lounge. All rooms in the Main Building are concierge rooms.
If you have booked a concierge room in the Sugar Loaf Lodge Building, you will have access to its concierge lounge. All rooms in the Sugar Loaf Lodge Building are concierge rooms.
If you have booked a suite, it could be located in any of the GF's buildings. Currently, suites have access to the concierge lounges (that has not always been the case in the past and I am speaking from experience here).
I hope you have a lovely stay at the Grand Floridian. It has become my favorite resort again.
