I'm not sure if you are expecting too much as this is the first time I have ever used a travel agent. I am using DW.com. I have had no issues with them, although I know other girls on here have.
Denise looked at numerous resorts and came back with quotes for each. She has booked, so far, 18 people's hotel stay and flights. She has also stayed on the wedding coordinator when I have a hard time getting in touch with them.
They are definitely more like travel agents than wedding planners, in my opinion, but they do offer to do STDs for you.
But, anyway, I am very happy with them...I would have not been able to handle booking everyone's travel and answering all my guests' questions...Denise saved me of that!
Good Luck
