I've looked into tours and I'm liking this one by Redline. I don't get seasick SUPER easily but I'm also emetophobic (have a fear of throwing up), so I'm contemplating whether or not to skip this step.
LITTLE BIG ADVENTURE SEASICKNESS SOFTWARE
In July 1997, both Electronic Arts and Virgin Interactive Software re-released LBA 2 - Virgin Interactive Software doing so under the name of 'Twinsen's. After leaving the protection of the Canary islands the swell picked up and let the boat roll from one side to the other. It was later re-released by Activision in June 1997 in both North America, and in Brazil, under the name Twinsen's Odyssey.
While reading reviews though, I have also noticed a sizable amount of people saying they got seasick? Little Big Adventure 2 (LBA 2) is a computer game made by the core team who created the first Alone in the Dark. Heading over to Hawaii in July and have been looking into planning for Maui section of the trip, and noticed most other people have included a snorkel trip to Molokini on their itineraries.
