We used Priceline to book our air last Spring Break for DH, DS (5), DD (3) and me. I won't do it again because of the layovers. We didn't get that great of a deal (busy season), and the layovers were a pain with small children (3 hours in Detroit - fortunately the Badgers were playing in the NCAA tourney and we watched the entire game in the airport!) Also, we wanted to leave on Saturday and return on Friday. We ended up with flights arriving in Orlando at about 9:00 p.m. on Saturday and leaving at 6:30 a.m. on Friday. I think it all depends on the situation you are in, but you need to be really careful if you want X number of days in the parks and don't care about the day you arrive and depart. We also had major fiascos at boarding time (seat assignments not together - leaving Orlando they wanted us to have our 5 year old by himself a couple of rows ahead of us <IMG WIDTH="15" HEIGHT="15" SRC="/infopop/emoticons/icon_redface.gif" alt="red face"> ), however, these were airline dilemma's ccaused by overbooked flights, not Priceline problems). Just my opinion
