Thanks everyone for the welcomes and suggestions.
I really have no particular plans outside of having to be in Reno for 5 days, I've done a lot of the major touristy things in the states before so I'm happy to go anywhere (at least once ).
After a bit of playing around I've got it down to $2.25/SC with a multi trip hnl-bgi, bgi-rno, sfo-aua and back to hnl. Are there any issues with multiple entries into the states like that? (you know after a couple days in various caribbean locations)
Thanks again everyone, looks like I have some searching ahead of me. And you guys can expect some dumb questions when it comes to booking these
I had no issues yesterday on my day trip to BGI but it was a little inconvenient. I went armed with wallet, passport, phone and iPad only so i was very light on luggage. Arrival at BGI i was met with quizical looks as to why i was there for 1 hour 10 minutes. It was more along the lines of "but you should stay and enjoy it here!" rather than me appearing shady. I was let into Barbados on the provision that next time i stay there's longer
Arrivals back at MIA was a nightmare (ill do a mini SC trip report later explaining that) but it was no big deal. Immigration agent noticed my place of birth in my passport and commented on how good the wines were from the region. We had a talk about the best aas in the state for the best wine. A really pleasant change from the usual attitude from the folks at USA borders.
That officially puts me a 3 separate entries within 90 days to the USA (3 stamps in passport) but no real issues. The concept of mileage runs is a little more understood by airlines and customs here. I had an involuntary re route and they asked why i was taking such an indirect route. When i mentioned i was on a mileage run, they laughed and said "well this gets you about the same number of miles@ and was the same number of SC's which they don't get here of course.
I'd spend some time in BGI if going there. It looked simply amazing from the air. I'm really kicking myself for not spending time there, but i will go back again and stay a while.
