Travel Republic is great I think because you can book your hotel, flight and transfer on one website and not be tied down like you would be if you went and booked with a mainstreet travel agent. If your flight home is at an inconvenient time you can book the extra night here before you travel and be sure you have your room on your last day. Whereas if you go mainstreet you have to ask at your hotel 2 or even one day before you leave if you can keep your room for the extra day only to be told you cant but there is a courtesy room that 50 other people will share as they are leaving at the same time (gross).
