I am getting ready to go on my second cruise booked through AAA, both I have made payments on, some as little as $25.00. My AAA TA didn't mind.
However I went in one day and had to deal with another agent I was on my lunch hour and my TA was tied up, this agent told me that she could only accept cash. I said well you give my check to my TA and have her call me if it is a problem. I called back later and my TA said she had no idea what that other TA was talking about but that she would certainly talk to her about it.
Its amazing what some people will tell you just so they don't have to do any work.
