Correct me if I'm wrong, but isn't there a fee involved for the bridge if they rent a golf cart and drive from North to South. That and the cost of a golf cart could run higher than the water taxi and I don't know of any golf cart that will hold 10 people (four at best if they are adults though I did see someone advertise a 6-seater). I could only afford a golf cart for a couple of days on my first visit because I shared the expense with my brother and I arranged it such that I didn't need one on my second trip. I did use a taxi a couple or times to get to/from Downtown or Papi's and, if memory serves me, each one-way trip was about 5 BZE. And, Taagbu, please don't take offense, as I try to get my lonely dollars to stretch as far as they can when I'm able to take a trip like this so it would be rude for someone to imply that because you are staying a certain resort you aren't concerned with how your vacation dollars are spent. Oh, wait, there are those on the island who will see you as nothing more than a way for them to make a quick buck. Luckily, I did not find most on the locals or businesses to be that way. Enjoy your trip!
