Countries that rely on tourism are starting to open up. Spain has just announced foreign tourists are welcome from 1st July. I got a ferry booked UK-Bilbao as soon as there was availability, 15th July. However, July - August is Spain's high season and they really needed to get it done. In the Grenadines, July would normally be low season so they may not be in such a rush. I'd wait until there is some definite news from SVG before booking.
