From what I am seeing there has never been more people here since I moved here 6 years ago. Not just everything booked, but 8-10 cars parked at most large beach houses. And with the 4th coming up, I see 3 holiday waves.
1 - Starting tomorrow, as the national holiday is Friday the 3rd
2 - Starting next Thursday for the long weekenders..
3 - Sat 7/4 as a heavy turnover day.
There are no official fireworks, but we have been hearing the amateurs for weeks and expect it to get louder.
The positive cases are increasing locally and by word of mouth as noted here. Stay safe as this will be a bumpy ride.
My only advice is hit the stores you have to at off hours.. Food Lion in Avon opens at 5:30....
