I just bought at BLT, easy access to Magic Kingdom and Epcot, on the monorail.
We decided on this resort because membership runs through 2060, also. I added up all the numbers and it was the resort that made the most sense "to invest into".
We figured many of the other resorts have already used 1/3 of its use years.
I would have LOVED to own at Boardwalk, which is my favorite. Walk to Epcot and Hollywood Studios, or the boat if I don't feel like walking.
It (Beach Club also) is convenient to any restaurant worth eating in , on Disney property. I love the back entrance to Epcot.
The buses make it so convenient to get to any resort or park, that the location is not SO important for going to the parks.
To me, being close to better restaurants is what makes the Boardwalk/Beach Club resorts a better choice. Parks become less important when you go there once per year (sometimes more)
It depends on what you are looking for. You will read ALOT of different opinions. This is just my opinion.
