We're planning on taking a cruise in May 2012 on the Dream to celebrate our 10th anniversary. I'm a very hands on type of guy when it comes to making my reservations. Is there any advantage or disadvantage for me to book the cruise myself through Disney as opposed to using a travel agent? Also, right now there aren't many discounts for the cruise we've selected, if a discount becomes available at a later date, is it possible to apply that discount, like you can with room reservations? Thanks!
