Hey Amanda, I'm getting married in Maui in August. I let my guests book their own airfare and hotel/condo. I've never used a travel agent to fly to Hawaii - I just sort of stalk the airfare prices online until I find the best deal. I've kept in contact with the guests I know are coming, have been checking airfare prices online about every other day, and have been text messaging or emailing people when I find a deal. We're staying in a condo on Maui, so I let guests know on the invitations where we're staying, giving them website info for the condos, so they can book there and stay as a group if they want. I really liked the idea of booking a "group flight" - where you can reserve a number of seats on a flight and not have to give names or pay for them until right before your trip - but it didn't work out because our guests are flying on different days and from different airports in CA....
