Bad news. Localized wear in an azipod thrust bearing is the cause for the dry dock.
Well, I guess its for the better to fix the problem as soon as possible, than have the Dawn limp around the Caribbean all summer long missing ports all the time.
Many have been complaining on other web sites because later summer fares for the same classification cabins on the Dawn are higher than the 125% refund/credit offer.
I think spending a little more to take a cruise which makes every port during the prime summer season is better than complaining over spilled milk.
