What we didn't like about CBR actually was how small it was. Yes, POR is VERY big and there is a lot of walking. As long as you make your requests reasonable, you should be able to get something close to the main buildings. In 2003 we stayed in Oak Manor (now the royal rooms) and it was about a 5 minute walk to the main building. Stayed in the mansions last year, too, and it wasn't too long of a walk. The wait times for the buses can sometimes be daunting. Generally MK and HS were the hard to catch buses. There was always one for AK and Epcot. It's only bad during park opening and park closing, though. Any other time, we never had a long wait for a bus.
