I didn’t say to disregard them. I’m just telling you what they mean. Hotel security only goes as far as their property line. After that you are responsible for yourself. Just like the warning labels on household products, they (the warnings) are scarier than they need to be.
It’s been a few years since we were at Natura Park, but I seem to recall that the point past Natura Park was about two miles and it was a very nice walk. And I think it’s about another two miles to the next hotel. I’ve walked to the point several times and never saw anyone but the occasional other walker. I never made it past the hotels going the other way. I seem to recall an obstacle that was somewhat difficult to get around. A marina or gas station and a fence or something like that …
Most stuff that ‘disappears’ outside the secure area (or inside it for that matter) are items left unwatched and unattended. However, as always, one has to exercise discretion and follow the normal safety precautions. No cash, no flashy jewelery etc. Maybe even find a like minded person and have a companion to talk to.
And like the last time we were there, I for one am looking forward to that walk.
