Hi Lorna,
Thank you so much for visiting the Disney Parks Moms Panel with your question. A multi-generation trip to Walt Disney World can be so much fun, and you have picked a great location to stay for yours.
Disney's Old Key West Resort is relaxing with its theme of the Florida Keys, and the villas are so spacious!
At Disney's Old Key West Resort, the buildings have two or three floors. My best advice when you are requesting a villa location is simply to describe your request. This way, if a specific villa you are looking for is not available, the cast members know why you made your request and can try to match it. I would suggest that you request a villa near a pool and a bus stop. That said, for a building that is close to a bus stop and a pool but away from the Hospitality House, you might do well in Buildings 19, 20, 54 or 56.
I hope that these thoughts are helpful for you, Lorna. Have a great time planning your magical vacation, and please do let us know if you have any further questions!
