Yet two more questions:
Did you use B&K's "paid" invoice to satisfy the requirement for "signed cruise itinerary?" Or, did you provide additional info?
What information did you include for "contact in brazil?"
Marc,
It has been two years but I think I used both B&K's "paid" invoice and the Regent "paid" invoice because the B&K invoice didn't show the itinerary. As for the contact information, I used "Regent Seven Seas Mariner Cruise Ship" in the "Name/Hotel" box on the application. I also used Regent's headquarters address, telephone and email on the application.
Hope this helps.
