The GF is setup with outer lodges. There is the main building, which houses registration, guest services, the monorail, shops and restaurants. There are 4 outer lodges which have the standard rooms. It's not very spread out though, I'd say the longest walk is from the boat dock to the monorail and that was about 7 minutes at a leisurely pace. Room views include garden, marina, lagoon and theme park. There are a few garden rooms that do overlook another building, but primarily, all the rooms are very nice. The GF will be undergoing a rehab over the next few months, so you may want to keep an eye out for any updated pictures. Standard rooms typically come with 2 queen beds and a daybed. All standard rooms have either a balcony or patio. Rooms on the top floors of the buildings are commonly referred to as dormer rooms. These are slightly smaller, but have a cathederal ceiling due to the slope of the roof. The balconies are different in these rooms as well. They are enclosed, with a solid railing and a bit smaller than the average balcony.
Some people like to request specific buildings to put them in a preferred area of the resort. Boca Chica and Big Pine Key are the closest to the pools, beach and main building. Sago Cay has some wonderful marina and monorail views. There's a little pathway beside the building that makes it very convenient to the bus stop. It's also closest to Gasparilla Grill (24 hour counter service/game room). Conch Key is closest to the resort boat dock and has some of the best garden views (IMO).
You have two ways to get to the MK from the GF. My advice, is to take the monorail there, but to take the resort boat back. The GF is the first stop on the return trip (shared with the Poly) and it's a beautiful way to see the resorts.
There are cabana rentals by the pool, if you are planning a day off from the parks. They can be reserved at 90 days out and come with some padded lounge chairs, fridge stocked with sodas, juice & water, tv/dvd, table and chairs.
The self parking lot is across the street from the resort. When you arrive, you definitely want to drive up under the Porte Cochere and drop off your luggage with bell services. Even if you're alone, they'll gladly take it and look after it while you park your car. If you are going to use your car frequently, you may want to consider valet. I believe it's up to $9 per day, but well worth it.
