jaccceee,
Research is key to priceline success. If you find 78 r/t air you jump on it and skip priceline, especially for non-stops. But when you can't seem to find anything other than those fares just under 200 dollars, priceline becomes a godsend. Say you have four people travelling and the lowest fare you can find is 179 r/t. But you get tickets on priceline for 100 total, you save 312 bucks. Then you hit a great rate at a hotel (eg of a rate you you see accepted often is 48 when you use the five dollar bonus money at Wyndham Palace in Downtown Disney), then your airline savings pays for five nights completely (factoring in taxes and resort fees). To me it is worth taking the risks if getting lousy flight times since I would probably just add more time to my vacation up front to offset the possibility of lousy flight times and I would still be way ahead of the game. If I get great flight times then I have an even better and longer time at WDW. IMHO
