My wife is not going to like this ... running around in golf carts is one of her favorite parts of our trips down there. We will be there on Saturday with the kids and are staying up North at Captain Morgans.
Before you ruin your wife's trip...You can take golf carts up north if you can handle the roads. We do it quite a bunch. Like it was said earlier, after Grand Caribe the roads deteriorate and get much more bumpy and sometimes wet, but very do-able (sp). And again, like it was said before, it is $5 USD each way/ $10 R/T to cross the bridge. But once you are in town the golf cart is good to go. From my personal experience I would say it takes about 15-20 minutes from the bridge to Grand Caribe and another 20 to Captain Morgan's.
