George Bush to GUA on United. Get a room at the Three Towers, (figure out that name in Spanish.) Try to get a reserved seat on the bus if you are going to Fronteras.
I heard a rumor of an airline flying (Spirit) from Ft.Lauderdale to GUA for cheap...
There are a couple of boats for sale there that I would like to look at.. Unfortunately, its just too hard to get to and has no resources (i.e. Surveyer).
The airfare to GUA from anywhere US is not that bad. The bus ride to the Rio is cheap as are hotels. I could do a round trip for a week with a thousand bucks if I wanted to look at a few boats.
