Crystal, I'm with you! I feel that way after 7 days, can't imagine doing the high life for that long. I think I understand now why people on the WC long for simple comfort food after a while.
I think the secret to exercising on a cruise is to be used to an exercise routine already. Guess I have to work on that before my next cruise, since I'm mostly a slug these days, except for lots of walking and my "moving exercises" (lifting, bending, carrying, running up the stairs, repeat until you're exhausted.)
