Jillymac, the overnight trip on the Offshore Express is a blast. It's got 5 dive stops, plus you can check out the booby bird sanctuary on your overnight stop. All 3 times I've been on it, we had dolphins either leading us out or bringing us back to AC and Capt. Horace and crew are great about letting you know they are around, so you can run to the front of the boat and get a good look at them!
