What if you book with one travel agency and find a cheaper rate with another agency later? Will they match each others prices? If so, is it a sure thing or a gamble that they will match the other agencys rate? Ive looked at so many agencies online and they never have the same rates (yes, it is a identical ship, date, room, no air). So Im wondering if I book with one, is it worth still browsing the others for their rates? Im not just browsing for Disney Cruises, but Celebrity also. Thanks
