Some of the most fun riding I've ever done has been renting a moped at a cruise ship port of call.
On a cruise about 10 years ago my wife and I came within probably 45 seconds of missing our ship courtesy of a scooter rental and going bombing around the island. Lost track of time, took longer to get back than expected, didn’t notice time difference between the ship and my phone (the main issue), all entirely things that were my fault, but, yeah, 45 seconds.
I’ve been a little mentally scarred against renting one on a cruise ever since lol
