Depends, is it too short, yes, is this your only vacation for the year or is it your 10th!! We did our first 3 day
DCL cruise in August, came home and said it was great, but wouldn't do it again because it was too short. A couple weeks ago, I realized we were do to come home from WDW on a Thrusday of Presidents week, decided what the heck, we could squeeze in another 3 day and the cost to change our air would only be $100.00 so we did it! But as DCL "veterans" we now know what to do and what not to do. We drove our selves nuts trying to keep the kids happy in all the programs, we felt they may miss something, but this time, we arn't going to go compando.!!
One thing, if you are just flying in for a 3 day or even a 4 day, do not fly in the morning of, fly the night before, we were so tired we only flew from Hartford to Orlando, the morning of the cruise, we were at the airport by 9:00am and to the port by 10:30! But we were so exhausted, we missed the Hercules show, slept right through it, made it to dinner and then back to bed! So do yourself a favor stay the night before, the easist is paying the extra bucks and stay at the Hyatt right at the airport, then do DCL transfers in the AM, but there are several other options.
