I havent been able to locate a direct answer to this question. If it helps with answers, we will be staying at the contemporary during the first part of april.
Yes, there are times with CR will share for HS and AK and the reason you have problems getting an answer is because it varies as to when. It's not always 100% of the time. DS is probably the only time it's 100%
I know on stays at WL we have gone by CR
I'm thinking I remember going by GF when we've been at CR
I can't remember if we've gone by Poly on any of those stays or not
Contemporary/Bay Lake (one bus stop for both) shares with Wilderness Lodge. Wilderness is the first stop, Poly second. The buses go to Animal Kingdom, Studios, and Springs. The Poly shares with Grand Floridian.
