Sorry if this question has been asked previously...but I just need to know. Back in Nov 2011 I booked 4 nights to CSA at the discounted rate for both me and my hubby and my brother and his wife. Our trip is for the end of May 2012. Recently, my sister in law decided she wanted to go an extra night. When she went to add it, the rates per night reverted to the current rates for all nights. So, not only did she have to pay for an extra night but also had to pay extra now for the nights I had already booked for them. Shouldn't the nights that I had already booked stay at that discounted rates and only the extra night be at that current rate? Did the TA do this correctly? When we asked our TA, we were told that unfortunately thats how Couples is, and any alterations that are made to your dates changes the rates. Please advise...thanks!
