I had to do this exact thing on monday. My TA wasn't getting into the office till 10am WEST coast time!

That's 1pm Florida time! I was definitely not happy with her.

I understand she doesn't start work till 10am but she should at least made an exception to wake up early and get this done for her customers. With the
free dining offered that saved the people in my party a total of $2380!!! Thats alot of money!! With money savings that size she should of had her booty up earlier!!
Monday morning at 4am I was calling WDW to make a new ressie because I just wanted to have a back up plan in case my TA screwed me. My TA finally did pull thru for me when she decided to call Disney 3pm Oregon time, not even 10am when she came in!!!
I fortunately was able to just cancelled my new ressie and kept my old reservations.
In the future I will just book with Disney directly or with a TA whose on top of their game!
As for my current TA, she however has lost my business for future bookings. This was the second time I've used her and the second time where she wasn't on top of things like should have been. For me two times is enough chances to give someone.
Now I've got to find a new TA, Crabby Patties!!
