POR is my favorite resort! I have stayed there 3 times now and am planning a 4th stay now. I have never put in a request for a room based on distance from the main building, only requests for theme. I have been put in the farthest buildings away from the main building and I have to say I really don't get why people get so caught up in getting a certain building, or area, or view, etc. I am in my room to sleep or shower. I never stop to stare out the windows and see the view. I sit on the benches outside and just take it all in. I have also found that in recent years that we tend to spend very little time at the main building. We get up, get ready and head to the closest bus stop. We grab breakfast at the park we are going to that day. We eat a nice lunch at the park before heading back to the hotel for a break. We may get off the bus at the main stop and have dinner at the food court and then have no problems walking it off back to our room to get ready for our evening activities or going to the foodcourt after our mid-day break for dinner on our way back out to the parks. People seem to talk about how hard it is to walk that far with a sleeping child and baby gear, etc. But why would you get off at the main bus stop when you have a stop close to your room no matter how far away you are staying in the resort? At the end of a long day, I always get off the closest bus stop and am back in my room within a minute or 2.
POR is a WONDERFUL and PEACEFUL resort that offers a nice respite from the hustle and bustle of the theme parks and I, for one, LOVE being stuck in the far reaches of it!!

GO!! Enjoy it!! Don't stress over location and schedules and ADR's. Vacations are for fun and relaxation... not stress over little things that aren't worth it in the grand scheme of things.
