Not surprisingly, I'm stopping by to quote Robyn and agree with her! These are my thoughts exactly. We just stayed at POFQ for three nights before our YC stay during Easter Week this year. We hadn't stayed in mod for over eight years, and after our brief POFQ stay, I appreciate YC/BC even more. (I really liked POFQ for a mod - it was great for its own category - just prefer deluxe.) But as usual, we were in Epcot nearly every night of that trip, and the bus to Epcot with six stops throughout POR was quite a contrast to our stroll through the international gateway at YC/BC!
In our experience over many years and different seasons, the bus from BC to AK and MK either goes direct or makes one stop at BWI. Either you're there at the right time or not, and in our experience, it's not any better at the other resorts. We've always found the CMs at the BC bus stop are particularly helpful. On the way back, there are a few stops, but we usually return in the late afternoon (not at park closing) so it's never crowded for us.
Overall, we're not fans of the buses - we'd rather walk. But we absolutely prefer the buses to driving. And YC/BC is a great choice because you can walk or boat to two of four parks.
Yay for a cab to DTD!
