I just called to change my reservations today. I was dead set against calling before I read this thread. I thought if I just wait, they may give me a better deal. Well, I decided to go ahead and call, b/c what did I have to lose? If they say no, then I would still be getting a call.
Well, the first person that I talked to put me right through to a CBR specialist. I just told her that I needed to speak to someone about changing my CBR reservation. I only had to wait about 5 minutes. Ireland was who I talked to, and she was very nice. I originally had used the CKO code for a king size room at CBR. My total per night was $109. She said that she could offer me other moderates for the same price, but that she had some other very good offers. She put me on hold and then came back and offered me the Polynesian for $7 extra per night. I was expecting to be paying $140 more for the seven nights, but she took into consideration that I was already paying for a king sized room and I would be getting double at the Poly. So, the total was $816 for seven nights vs. $769 at CBR. She did say "We are calling people according to when they have reservations, but since you called in, you got lucky!!" So, do not hesitate to call. They do not mind it of you do!!
