Just curious. I don't travel often but having been in the travel industry and trying to work with third party sites from the Hotel's side of things I do not use them when making reservations. I may use one to look up what hotels are in the area but then I always go directly to the hotel's/Airlines sight to make those reservations even if it means paying a bit more. This way I am dealing directly with the property for any issues and not trying to deal with a third party.
