Please forgive me if this has already been mentioned, but I didn't find anything about it when I searched.
Apparently the Lana'i Visitors Bureau has been sponsoring a "New Media Artist-In-Residence" program, sponsoring travel bloggers to visit Lana'i and write about their experiences. So, it seems that there is now a wonderful wealth of new information available for you to delve deeper into Lana'i and the resorts, activities, dinner options, etc. that are available!
