Hi All, I'm updating my post- it took me days to get through to an agent. I had booked through Costco travel and called them first. I never complained about the uber long wait or my multiple calls and just asked nicely. I was fully prepared to possibly pay $100 per person and a rate increase if necessary.He did not charge me any fees and changed my reservation, and to make it even sweeter, the price of my rooms had gone down! I hope anyone else in this situation has the same results.
