Except MK, Epcot, TTC, Poly, GF, Wilderness Lodge and Fort Wilderness.
J/K I'm sorry your experience was so subpar. I will add this, mostly to the OP - when I stayed there, it was in a 1BR Villa. I didn't even think about the studios, and I know other people besides TheBeastMom have now pointed this out, but the BLT studios are amongst the smallest rooms onsite, even smaller than any of the mods. If the OP is staying in a studio, it could get to feel cramped fast especially if there will be more than 2 people in the room (and with 4 people in the avatar, I'm guessing there will be). While I certainly hope that's not the case, it could be.
I don't think the deluxe resorts share buses all of the time, or just during slower seasons to save money. To the OP, when you arrive, I'd suggest asking the front desk what the situation is there. If all the monorail resorts are sharing buses, and IF you're going someplace other than MK or Epcot (like the Studios, AK or DtD), and IF you don't have your own car, you may want to consider taking the monorail to the TTC and busing from there. It's an extra stop, but compared to the two potential extra stops on the bus line, it might be a better use of your time. But since it seems that the Contemporary is always the first resort back, I'd use the buses to the resorts on the way back to your room FROM the parks or DtD.
Thanks for the tips. The bus sharing seems like a bit of a hassle, so we'll need to figure that out. Going to the TTC may be the best. Room size may be a bit of a concern. We've done studios before at AKL, SSR and BCV, but we've had 1 bed rooms for the past few years, so going back to a studio will be an adjustment. What we wanted to do is one year of studio to bank a bunch of points and then do I bedrooms for the next few years. Thanks again.
