Hi Debra,
You are going to love your stay at Disney's Old Key West Resort!
You can find out more about the Resort itself and what it has to offer
HERE
My family stayed in Building 48 towards the end of 2009 and thought that it was a great location. It was situated in a very quiet, relaxing area right across the road from South Point Bus Stop and in very close proximity to one of the Resorts quiet pools.
Hospitality House, the launderette and main pool were only a short Bus ride away.
If you wish to stay in a building close to Hospitality House, then you would need to request either buildings 11, 12, 13, 14 or 23, 24, 25, 26.
One of the things which we loved about staying here was being able to catch a Boat from the Resort to Downtown Disney. It is so relaxing and makes a lovely change to getting the Bus everywhere. I would highly recommend that you give it a try during your trip.
I hope that you enjoy your stay in this beautiful Resort as much as we did!
