Just returned from trip to Barbados. Can't help you on route never gone that way, however, I.A.M. Jet is the FBO and they are very good, contact them via Email give them your requirements and they do the rest, use
[email protected]
Something new for customs, You are required to send passenger and crew info to CARICOM at
www.caricomeapis.org/ no later than one hour prior to depature.
I.A.M.will also suggest and arrange hotel. I recommend either the Hilton or the Accra, with the Accra been within walking distance of good pubs and eatery's.
Hope this helps
