BEYC
You have access to all the North Sound:
BEYC water sports
Saba Rock
Prickly Pear beach
Necker Is (snorkeling)
Leverick Bay (water taxi) which gives you:
Levering Bay pool, great restaurant, laundry, watersports
and from there via taxi
The Baths
Top of the Baths
Coco Maya
Etc

Also, you'll be hunkered down for a few days at some point due to weather. No better place than North Sound. The water off BEYC is flatter.
