The Villas at Disney's Grand Floridian Resort - how long a walk to the mono-rail or boat to MK?
Depends on the speed of your walking and assuming this from the elevator since the walk from any individual villa may vary. The monorail is maybe 1/2 a mile to the actual enterance (this includes going up the stairs in the main building). The boat is possible 3/4 of a mile away.
How is the transportation to the parks?
Transportation to MK is usually wonderful- the monorail is normally faster to get there and the boat faster to get back. DHS and AK take a bus and share that bus with other resorts most of the day. I give myself 30 minutes plus 15 minutes time when catching a bus and normally arrive before that 45 minutes is over. For Epcot you have to take the monorail (or walk through the Poly) to the TTC and then use the Epcot monorail. It also normally takes less 45 minutes to arrive at that park and a little less time to arrive back from it.
Bus from the DVC to the main GF building?
This doesn't exist you walk the 1500 feet under a covered walkway.
Bus from the The Villas at Disney's Grand Floridian Resort to the Parks?
You have to go down to the main building for all buses none of them come directly to the Villas.
Please tell
Thank you
