Donna -- it is a lot of money and I understand. I brought up the topic around here and was veto'd. DS13 said it is to celebrate his Bar Mitzvah so it really should be Disney.
The 75 day mark is Monday. Would you be able to contact your TA over the weekend if you decide to cancel?
I don't think so (as far as contacting TA) over the weekend... I asked DD13 yesterday if she was excited and she just rolled her teenage eyes at me and said "Mom, you take me on so many cruises what difference does one more make"
which made me think 1) why do I bother and 2) why pay more for DCL when it is me who wants to cruise 24/7/265 
I could save so much $ by booking Costa (cat's outta the bag) that I could pay for a spring break (non DCL, of course, since March 27 rates are astronomical) cruise.... but what the heck. Might as well live large and do Disney while I still can and then try to figure out later how to also do a spring break trip.
if it was a couple of days ago and I hadn't paid in full, well, then, that'd be a different story....

and I am sad over that - but still tickled pink that I will get our last Disney Cruise with DD before College.....
laundry folks, too. The one that got me was the upset lady when someone was FOLDING her clothes that they had removed from the dryer so that they could use the dryer.
