I've always found Sundays to be busy at Willy T's. Many charterers arrive in the islands on Saturday and leave the dock Sunday AM and Norman Island is a popular first stop (when you are on a boat you haven't sailed before, NI is an easy reach).
Willy T's is often filled with locals on Sunday afternoon and the visiting sailors take over in the evening.
I recall one Friday night it was also quite wild as it was our last anchorage before heading back to Roadtown on Saturday.
The Bight has plenty of mooring balls available as well so arriving late is not usually a problem either.
