I haven't had any problem changing my ressies - went from room only AP rate to a resort magic with special code. Since that is no longer available, I compared prices yesterday for a second room that I now need and got the best price with Fall Fantasy. Before I call I make sure that I have the breakdown myself. I price out the ticket option that I want, what I know the 'flexes' run (if there are any with a particular package), and I always ask for 'without breakfast' on the FF because we're not big breakfast eaters. Then when I call I have my calculator right there so I can take the price, deduct what I know I have to pay for tickets and flexes and divide the balance by the # of nights. Once I know what I'm paying for the room, I always ask them to check the DC price on the room and the AP price on the room and see which way is cheaper. I booked 2nd room at AKL standard for $153 - now I'll sit back and hope for a postcard or a code for late Aug., but I wanted to be sure that I had the room reserved for my dates. If you get a CM who doesn't seem very helpful, tell them thanks, hang up, and call back until you get one who wants to go the extra mile for you - my experience has been that overall the CMs have been willing to take the time to try and get me the best price.
