I used them in 2022, I pre-purchased via expedia way before I left and purchased insurance online as well. Spent probably an hour, maybe 2, at the counter as they said the insurance didn't cover (apparently the online you have to pay out and maybe get reimbursed later) so signed a waiver with retainer. Got a mini-van as we had whole family but wanted to dive. Paperwork said zero sand in vehicle (um it's an island!) and said something like no diving equipment. More discussions - eventually (in very broken English and I'll admin I don't speak another language so don't hold that against them) I think they said it would be ok. Got the mini-van, drove all over the island for a week, returned with no issues. Did have to fill the one tire but had a filler end in my save a dive and filled it up with a tank from the dive shop - it held all week so was just low to start. So not great process getting the vehicle but all worked out. Luckily I've never had an issue/accident while in the islands so really can't speak to what it would have been like if I had. They definitely had a local process, so ordering online may not be the best route - but I wanted to ensure we had a vehicle when I got there.
