Wow, this thread is getting pretty hot n heavy....
Some of this has been said - here is my opinion
It all depends on which parks are key and whether you have a preferred method of transporation - i.e. Monorail, Boat or Bus
If Epcot is #1 and you can walk distance because before 11am you will have to walk through part of the World Showcase to get to anything that is open then go BCV/BC/YC
If MGM is #1 and you can walk then go BWI/BWV - there is a boat as well that goes there (and to Epcot as well) but to Epcot you will still be on the WS side as opposed to FW side (main entrance)
If MK is #1 and you can walk then pick CR - from North Wing or Tower about a 10 minute walk to the MK at a moderate pace
If MK is #1 and you like the monorail then GF or Poly works great followed by CR
If MK is #1 and you like boats then go with WL and stay in the North Wing near the boat launch, and use bus for the rest of the parks
If Epcot and MK are tied then go with the Poly for easiest access
Finally you can have a stay at AKL and use the bus system which is very easy and reasonably timely
My goodness, seems like we shold do a spreadsheet matrix with all the possible combinations!!!
Thanks
