Thank you everyone! I really appreciate all of your insight and thoughts so far! I haven't made a final decision yet, but I will give you a bit more info about our vacation...
The last few years at Disney have been girls trips with just me and my mom. We're not park hoppers, and we typically do a park every other day, with down time, Disney Springs and dining at other resorts in between.
We really loved the grounds, atmosphere and Royal Rooms at POR. Our main issue was the bus transportation... especially at the end of a long park day. It took us almost two hours some nights just waiting to get on the bus (sometimes it was the 3rd or 4th bus that we finally got on) and we were always the last drop off at the depots. I imagine this will be worse since it will be during a more busy season.
I really like the idea of the boat transportation to MK from WL, and I imagine this will eliminate some stress during our trip. I read that you can also transfer to the monorail to go to Epcot... this would be great since we are planning to go to Epcot and MK twice! We also visit the GF for tea every trip
A deal breaker, although this might sound strange, would be the heating system in the rooms at WL. We're from NY, and when I we were at Disney in December two years ago it was freezing at night! Lucky POR had heating in the room! When we stayed at AK last October the room had really no heating options... it would only stay on a few minutes then switch to AC. We just couldn't set the temperature in the room. We even had a maintenance worker try to adjust it, but it didn't help much. They must've thought we were crazy asking for heat in Florida, but the room was really cold at night. Anyway, I'm curious if AK and WL have a similar heating system? Or if anyone has had issues during the winter?
