How are people able to leave the area for the summer? Is your job seasonal, like a teacher? Or are you unemployed currently but with significant savings?? I'm just surprised anyone can do this. But happy for you. It sounds nice.
I would pick a local beach in MD, VA, or NC and rent for six weeks or something along those lines. Pick something several blocks away from the beach to save money. Maybe pick a less populated beach area, too. Will be cheaper and safer. I'd wait another few weeks before booking, though, because there should be an announcement about reopening (or not) things this summer.
