We love the exumas, but can be a tough spot to bareboat compared to BVI. I don't know where the base is, but Georgetown is the main city in Exumas.

Some differences:
1. Groceries are mostly available in Georgetown and some days the supplies vary. You can get fresh fish from locals.
2. Tide. You have to pay attention, you will run aground, it happens.
3. You can just hang in the water with a beer unless you have a line attached, you will drift fast.
4. From Georgetown everything is generally downwind, then upwind. So not a lot of great sailing. A one way from Georgetown would be great. Or heading to Long Island from Georgetown.
4. The beaches are much better than anything in BVI
5. You will find occasional beach bars.
6. In June the crowds will be thin as the cruisers will need to be heading out for Hurricane season insurance requirements.
