Just so happens I have a story for this topic ....
When my wife and i took our kids to the El Cid resort in Puerto Morales last fall, we were eating at the lunch buffet one day and my 8 year old daughter noticed my wedding band was not on my finger. My wife and I looked at each other in horror, summizing that it must have slipped off somewhere in the MASSIVE multi-tiered pool/waterpark MAYBE. I was really upset about this as I had no idea it wasnt on my finger anymore.
My 2 sons said they would get out their snorkel gear and look in the pool, but this was beyond a needle in a haystack scenario. And that was IF it had come off in the pool. I fully expected to never see it again. Low and behold after 2 hours of snorkeling my 11 year old came to me and asked me if the one he found was mine

Lol. It had gotten wedged in a filtratation cap under a waterfall !! I still can't believe he found it....

I was VERY lucky that he found it, but will never again where my REAL wedding band on vacation (Nor my watch either) . On our last trip to Desire, I wore a ring (That we bought at El Cid ironically) that would not be the end of the world if it went missing. My wife doesnt ever wear her rings on vacation. Just not worth the risk of losing. My recommendation is to replace it while you are away with a non sentimental substitute or to leave any/all quality jewelry at home.
