I've used both MJ & DU in the past. Our trip of March '03 and Dec. '03 and they found us a great rates each time with excellent service. We tried DU for our Sept '04 trip & they really spoiled us with the iteniary & restaurant reservations. For our Jan. '05 trip MJ couldn't get us the PO-FQ at the AP rates but DU could, go figure. But you won't be disappointed with either of them.
