Bob, I have been using them to book Coco, two times a year for I don't know how long. I always felt that it was a little silly that the rates that Onestop gave were MUCH cheaper than booking through Coco direct. That being said, if I can't find prices like I got through onestop, I unfortunately may be looking else where. We love Coco, but the prices offered on their website are pretty pricey in my opinion.
