Except after heavy rains, you can make it Portofino (and even farther north) by golf cart. However, it's a L...O...N...G drive, and by the time you get there on an electric cart you're almost out of charge. After dark it would be a real pain. Lights on some of the carts are lousy, the golf cart path has holes and water traps, and you could miss a turn or drive into a ditch. Water taxi or other boat is really the only realistic option to/from town, though from Portofino you can walk to some of the other resorts and restaurants on North Ambergris.
