I did the hotel/park thing in 2003, I got shot glasses...err Toothpick holders as they were labeled. I was staying at Grand Floridian here is the route I took:
mono to contemp, boat to wild lodge, boat to ft wild, bus to DTD, boat to Pt Orle, bus to typh lgn, bus to POP, bus to Sports cmplx, bus to allstars (all 3), bus to AK (park), bus to AKL, bus to Bliz BCH, bus to coronado, bus to MGM, bus to Carrib, Bus to epcot, walk fut wld, walk wld sho, walk yat and BCH, walk Brdwlk and ESPN, walk swan, walk dolphin, Bus to TTC, mono to Poly, boat to MK. Better bring your walking shoes. spent about $170 for all. Did not do Old Key west though. If you want to do it quicker split the list like Epoct - north to MK and EPCOT East and west (AK - DTD)
and meat back at Epcot for Lunch/dinner and illuminations. It took me a good part of the day. The Wife and kid thought i was Crazy, I just didn't want to spend the day at blizzard beach that's all...Can you say "look mom there's a beached Whale!!!"
