I keep reading about getting transferred to guest services and changing your reservation with a code past the booking window. I have found out that my husband may not be able to get off when we had planned to go. I have a postacard deal from january booked through AAA - the 40% off thing. My aaa agent booked it for me. Has anyone had any luck getting one of these codes changed through a TA? and just incase this is worth pursuing, can anyone help me find the dates it was originally good for so I can try to pick something else?
