lanai ferry tour?

question
I plan to take the ferry from Maui to Lanai for a short visit to Lanai, just for the afternoon. We will be coming to Maui by Cruise ship and I don't want an expensive shore excursion from the ship that last all day. Can we just explore a few hours?
When I arrive there by ferry, is there transportation in to Lanai City or any other short tours around this island.
Or is it best to rent our own transportation, like a jeep, for just a few hours exploring.

answer
Ok, it seems there is a very nice beach with good snorkeling within walking distance of where the ferry drops you off, so that is an option. The only taxi service on the island also sends a shuttle down to meet the ferry so you could probably get into Lanai city or maybe the other hotel that way, although it doesn't seem like they go anywhere else. If you wanted to go anywhere else you probably will need to rent a car or take the guided 4 wheel drive tour the expeditions people offer. I checked the prices and they really are reasonable for the island - although they seem high, that's how it is on Lanai. good luck! Lisa
