I'd take 14 days if you have them - stop to smell the roses on the way. I'm in Carriacou now and it is awesome. As are the Grenadines, St. Lucia, Martinique, Dominica, Guadeloupe, Antigua, St. Kitts & Nevis then St. Barths and finally St. Martin.

It can be done in 3 days or less of non-stop sailing; but that's boring offshore sailing and I've only done that when I had a schedule to keep (or, back during COVID days, wasn't allowed to stop on the way...).
