Visiting Big Island mid Oct. to celebrate 30 years of wedded bliss. The last night we are on the island is Monday 10-21. 2013. Our plane leaves KOA at 10:45 pm. Does anyone have an opinion as to whether we would be able to take the Spirit of Kona sunset dinner cruise (5:30 to 7:30pm) from Kona pier, drop off rental car, check bags, security and still make flight? Would appreciate drive times from pier to airport, ease of dropping off car etc. to help make up my mind. Thanks for any advice!
