gosh Jenny! Sorry to hear that. I chose my TA b/c she will create a Destination Wedding Packet of information for me to give my guests. Then my guests contact her directly to make their reservations. She'll also keep me updated via a guest list spreadsheet as my guests make their reservations.
Can you change at this point and have another TA handle it? If not, send a PM to Tammy. I'm sure she can provide some guidance.
