Maybe I've gotten lucky but every time I've taken JUTA I've always ended up with 1-2 other couples/families and it was pretty quick and comfortable.

JUTA seems to be more enjoyable when it comes to transportation than booking with the all inclusive hotels, a lot of them use really large buses that are packed with people.

Enjoy Jamaica for what it is, just remember that a lot of stuff is on Jamaican time :-p
