I'm just back from a long weekend on Lana'i. I believe Expeditions sells Lana'i tour packages as part of a day-trip. My weekend was spent relaxing by the pool, a spa treatment, snorkeling, some hiking, attending the Pineapple Festival and an afternoon and dinner at Ko'ele.

Honestly, Lana'i is not a place for touring around - there are limited sights to see there, most are accessible only by 4WD which you can rent as part of an expensive day package. Snorkeling is nice, but I've seem the same fish and coral off Black Rock at Ka'anapali.

Lana'i is a place to go to relax - no chain stores, no chain restaurants, no traffic, no hustle/bustle, no stress. I'm not sure I would recommend the day trip..a couple of nights there is a much better idea, but the hotels are very expensive.

Also, if you are prone to sea-sickness, the water can be very rough and the ferry gets tossed about quite a bit - I'd recommend getting a prescription for Scopace (scopolamine tablet, not patch) and dosing up at least one hour before departure...and sitting downstairs at the rear of the center seating section.

Also, I strongly, strongly second the advise re: Pricelining a better hotel near Kihei or even Ka'anapali. Use biddingfortravel to understand the bidding process and get an idea of current bid rates.
