I guess it depends on your length of stay. Too short or too long and it's not worth while. I go to Jamaica to be on vacation. Don't mind doing most things by myself so I like the DIY but as some point I just chalk my troubles up to being on vacation and don't bother. To each their own I guess! I'd probably rather buy the rum and Juices as needed at the rate I drink the punch, but I'm just me... with a group, a gallon might not last long!
