When we came back from our last (first) cruise... I had sea legs for about 4 days.... that's crazy stuff. But I had already experienced that going fishing on the river with my dad when I was a kid... we'd be out all day and when we got back to the harbor I'd start swaying back & forth.
I thought is was cool back then... Now, not so much!
Do you think the longer your cruise, the longer your sea legs? Last cruise 4 days... next cruise... 7 days.
