We were impressed also, but I think it could be a matter of right place, right time. We walked up, checked in with no wait, walked over to the lines, there was no line- were escorted to the bus immediately. We sat in the bus for less than 10 minutes and were on our way. We were checked in at the POP (even with a room change) and were on our way to EPCOT within 1 1/2 hours.
If you got there just after a bus left, or had a bus that stopped at a couple of resorts first, I think it would take you longer.
