That is a big difference!

I'd probably make a decision based on what you want to do during the day and see what fits.

If you've never toured Virgin Gorda by car, do that. If you have, then try something different.

And if the goal of spending two nights in the north sound is to slow things down, that can also be done very nicely in other spots. We've often spent a couple nights at Norman (swapping anchorages there each night) and spent time at the Indian's, caves..etc. We just moved over to a nearby spot for the day and then back for the night. It was very relaxing.
