We are booked for POR for 5 nites starting 5/13. I considered changing to YC - it is our favorite and also most of our meals seem to be at Epcot or Epcot resorts. It was going to be almost $1200 more for the five nites, so I hung up. Called back later to see if we could just do the last two nites at YC figuring that would be $400-$500 which I could do. They explained the whole split stay problem with the package and then a room only ressie for YC at the end and how our dining plan wouldn't carry over, and I get it-- but I know people must get moved sometimes- what if we really hate staying in a moderate once we are there- will they really not let us upgrade to a deluxe and just pay the difference if there is availability??
