I'm spending 3 weeks in Puerto Rico with an 8 day cruise in the middle. Are gas scooter rentals common and affordable in the area similar to SE Asia? The self guided tour by scooter is my favorite traveling activity!
Scooters aren't the most common thing there. It's mainly cars, suv's, and motorcycles. It also depends where on the island you may be at.
I'm not too sure with the comparison of prices, but I know that scooter rentals are not overpriced and fairly reasonable in SJ.
