Perfect! Collared shirts or polos, chinos or even nice shorts, shoes or attractive sandals (preferably with socks), but not tee shirts, holy jeans, flip-flops or bare feet (unless you want to look "bien naco" - like a yokel - and get lesser service. Maybe small embroidered logos, but not poster-sized cartoon characters. That's pretty much the travel definition of "casual elegance" used by lodging and cruise companies (like Windstar Cruises), and what I will be wearing later this month in Cancún and Isla Mujeres. Tizzette said it more succinctly, and Sylvia still has me laughing on the fl00r.

Could have little crocodiles on the chest, but those are soooo passé.
