I would heartily agree with Todd about the Honolulu traffic as we made that mistake on our first trip. The rest of Oahu was fine but we sat in hours of traffic in Honolulu. And if you can rebook additional time on either end I’d do it in a heartbeat. The more the better as there’s so much to see and do. The sites on Oahu are worth seeing at least once but the Arizona was absolutely incredible and we spent the better part of a day there between the Memorial and then the Missouri and we didn’t even have the air museum as an option. The airline fares to Hawaii are high and the trip, even from the middle of the country, is arduous. It pays to see and do as much as you can while there. There’s a lot I’d still like to see and do again throughout all the Hawaiian Islands but after the last flights I swore that’s it - no more returns. But that’s me and I’m not wild about flying and the 3.5 hours to SXM seems like forever to me……🙂🙂
