I've concluded that three straight days at sea is a bit too long for me...weather wasn't warm enough to be outside for too long.  However I am on day 6 of seeing New England in a minivan with 4 days to go and I so wish I was at sea....people who think a ship is claustrophobic ought to sit in a minivan from Maine to New Hampshire to Vermont.  Beautiful as the fall foliage is, give me the ocean any day of the week...just not too many sea days in a row.
