I'm soon going to Guadeloupe, Dominica and Martinique and am considering doing a day trip from Guadeloupe to Montserrat by ferry. I do not plan on bringing my passport, as my (Swedish) ID card is valid for Guad+Dom+Mart (Guad+Mart obviously, Dom too according to their head of immigration, whom I asked via e-mail)
Montserrat remains the question, as I haven't been able to find a proper e-mail address to send a message to.
Reading through the Montserrat immigration act, it says you do not need a passport if being a passenger "in transit by sea or air who does not intend to remain in Montserrat for more than fourteen days provided they are in possession of through tickets to some other destination"
It's on page 71 of this document http://agc.gov.ms/wp-content/uploads/2011/10/13.01-Immigration-Act.pdf
My question is: would a same-day return ticket to Guadeloupe be acceptable for this purpose?
