anyone know how full these sailings get? is it usually a full ship?
I've done 3 TA's with DCL and none of them were crowded. These sailings usually have a lot fewer kids than normal so even if the cabins are full, there are a lot fewer people sailing. But the adult areas can be a little more crowded than usual but we've had a great time every time!
As far as weather, it's really a hard thing to predict. But this year's WBTA there were several big storms in the Atlantic or forming in the Atlantic while we were out there and we didn't have all that many rough sea days. The WBTA the time before when DCL did it, the water was like glass!
