Well, some rooms are and some aren't. Last time I stayed at the Poly, I was in the long house closest to the GF. That's quite a walk from the TTC. But the real point is, why should a bus go from the GF to the TTC withouth FIRST stopping at the Poly on the way. For heaven's sake, you're driving right past it!
I agree with the PPs who commented that you really don't want to tick off your higher end clientele. They may be in the minority numbers-wise, but not in the "profit per guest" column. Making people walk from resort to resort while they are dressed for dinner or a reception at the GF conference center is not a good idea. I am not saying that they have to run monorails for this small number of people. But there is no good reason why Disney cannot run a few shuttle buses (like the ones rental car companies and parking services at airports use) around in a circuit stopping at every resort, door to door. Let's not forget. I can stay at the Dolphin and take one of their limos door to door to Victoria & Albert's for less $$$ than I can spend to stay at the Contemporary or Poly and have to bus back and forth to the TTC, with a few hot and humid walks thrown in for good measure.
