Some CMs might try to give you a price adjustment. It happened to me with our August family stay, one CM kept trying to move me from WL to a DVC with a price increase. Then when I wanted to explore AoA suites as an option, she quoted me an additional $200. I ended up taking it (had been on hold most of the day at this point and was tired). Overnight I thought about it and was not happy since it came to a ridiculous amt per night when I looked at our original WL rate.
So I called back the next day. I called GS directly and that CM was surprised I got charged, and she fixed things for us and refunded that $$ and moved us to Poly. (Of course that got changed today

).
