Just remember...it's not too late to switch TA's And I know there's got to be a way to handle the transfer without losing your deposit. I'd bet money on it. And I only say this because when we were originally booked to go to Beaches Negril, we booked with another TA. She was great in the beginning, but then once we made our deposits it was harder to reach her and get answers. So I talked to a couple of TA's (including TA Jennifer) and both assured me that the transfer could be made. Because we needed to switch the date and the resort, I just ended up cancelling our original booking, and then switching TA's, so I never actually had to transfer the exisiting reservation, but like I mentioned, I know it can be done.
You say you aren't happy with your current TA, so I really would look at switching now, instead of when it gets closer to your date. At least you know TA Jennifer would make sure everything is taken care of for you. JMO
