We were on the 4/10 western cruise. On the cover of the navigator, it stated "suggested evening attire: mexican, tropical, casual (no jeans please)", while all the other nights said no jeans or shorts. However, on the back of the navigator, where it lists your dining options, it stated "suggested dress: tropical, casual-no shorts or jeans please". I think if you just read the cover you would assume shorts are OK, but the back still requests that you don't wear shorts. Seems a little misleading to me. I would say more people wore slacks than shorts, but we did see a mix of both.
