Just back last night. We stayed in room 2326 for 5 nights. It was wonderful. Out of my 4 WDW stays so far this year, this room and resort were so much better taken care of than the others. It restored my faith in Disney.
Room 2326 faces the BWI quiet pool and is a corner room, same level as the lobby. I loved it! It was immaculate.
We love the Epcot area, but always stayed YC/BC for the pool complex. I think i actually now prefer the BWI b/c of the great entertainment right outside at night. Of course, it is accessible easily if staying at YC/BC but not as easily as already being there.
The only thing I found to be problematic, is that I couldn't find a place to grab a meal in the rain. We were planning a MK evening and wanted to grab an early dinner before leaving when DD3 woke up from her nap. Well a FL afternoon storm blew in at that time, so we just hung in the room for an hour until it slowed down enough to venture out for a bite. We ordered at the pizza window but then there was nowhere dry to sit and eat. There is no reason to avoid BWI b/c of this, but it would be ideal if they could find a small space to have some sort of indoor quick service.
As far as walking to DHS, it took me exactly 15 minutes from my room to security at DHS. I forgot to time my walk to Epcot, but it was even more quick, and I had to go back to the lobby to take the elevator with my stroller first.
Can't wait to go back!!
