I like more time on the sandy beaches and at the beach bars, so my preferred trip includes at least 2 full days around Jost. Having Sandy Spit or Sandy Cay all to myself is HEAVEN.
Monkey Point was not good snorkeling last Nov, but the Caves were awesome. I guess things are always changing with conditions. I really enjoyed the SUP around Saba. You didn't mention evening entertainment needs, but our trips are always planned around whatever live music may be available on certain dates, as well.
Hope you guys enjoy your trip! It's certainly addictive.
