is the electricty in the places they are going the same voltage as in the country they are from??!! This might be a very important issue if
they have any thing electric or electronic...will they need adaptors?
In the Caribbean each country has a different currency (money)and there may be different electric current too.

It is important to have a contact person who is available..
we just had problems due to a travelling musician who did
not get messages because he was on the road when the time
came for important decisions or answers there was no response.
Do your friends have a demo recording to send ahead of them to
let the folks know what they sound like? For us radio play is
an essential part of advertising the gig.

if you are contacting venues in the islands, your phone bill
could be gigantic! are you ;able to make contact thru e-mail?

Let us know how this turns out..

and if the instruments and players all survive,
we may all want you to book us to lthe islands
in the winter!!

check into the airline policy on instruments..
some allow you to carry on, others do not..
if the instruments need to fly in the baggage
compartment be sure they have adequate armor!
