So not including families with kids, do you prefer a quiet cruise with your SO or a fun group filling a bigger boat?

When we chartered in the BVI's a few weeks ago (just the 2 of us) we discussed who we could invite to fill a boat. But then we saw so many dinghys loaded down with 8 adults and thought it must be much easier to not have to coordinate a larger group for everything every day of a cruise...a cruise that in my mind should be a relaxing vacation.

I guess costs would go down significantly with a group?

Thoughts on pros and cons of each?
