I didn’t travel all that way to walk around in the jungle, size 15 feet reduces the chance of rental fins, I had to use a jacket b/c but this is why my reg, computer and a pair of fins were in my carry on.It happens. I've yet to have that happen to me. Most places have plenty of distractions should it happen to me. In fact, most places have plenty of rental gear too! Yeah, I like my own gear, so I'd probably just occupy myself with local flora, fauna, and geology.
