DU has been awesome for us. We've booked 8 cruises and 3 Adventures By Disney trips using DU and all has been flawless. When I want to make a change, add an extra night, just have a question, whatever... they respond very quickly - always within 24 hours, almost always within just a few hours! We've never tried another agency - started with DU because of these fantastic DISBoards. We really appreciate their sponsorship as each of our vacations has benefited from all of the pre-info we gather from the DCL and ABD boards. Also can't complain about the nice on board credit they give us!
