on-line travel agencies

[ellamom]

I have booked the Sheraton Vistana Resort for September through the Florida Travel and Tourist Bureau. I was given a rate of $104 per night. I have a few questions. Has anyone ever used this on-line company for their vacation? I did find a cheaper rate through the hotelkingdom site , $99 a night with the seventh night free. Although this is a better deal, I hesitate to change my reservation because I had read a post regarding a double booking problem at the other Sheraton Vistana, the village. Finally, I was curious if I could possibly find an even cheaper rate. Any help would be greatly appreciated.

Thank you!inkbounc
