We took a day trip to Lanai and booked the ferry / jeep combo through Expeditions. Cost for two adults $ 288.80, which included adult ferry round trip for 2, jeep rental, and shuttle for 2 (to Dollar Rent a Car and Harbor), tax. In Lahaina we parked at the Wharf Cinema Center ($5 all day parking with ferry ticket stub) and got on the 6:45am ferry to Lanai. The 45 minute ferry ride to Lanai was beautiful and calm, shuttle picked us up at Manele Bay to Dollar Rent a Car. Very quick, efficient service, friendly staff (Expeditions and Dollar). Expeditions called me the day prior to our reservation to notify us that the road to the Garden of The Gods would be closed due to rainy weather so we could cancel the jeep at no additional charge but we decided to keep the jeep so we could still explore other areas of the island at our own pace. While on Lanai we had breakfast at Blue GInger, visited a friend who lives in Lanai City, checked out Shipwreck Beach and the petroglyphs, Keomoku Village and church, checked out the shops at Dole Park and purchased souvenir trinkets and art from Mike Carroll's gallery, checked out Hulopoe Bay, walked to Sweetheart Rock, and drove to Kaumalapau Harbor. We returned the jeep at 3:15pm to get on the 3:30pm shuttle back to the harbor to get on the 4:30pm ferry back to Lahaina. The ride back was VERY, VERY, rough due to large swells. Great way to island hop!
