Usa East Coast beach town

Looking for an east coast destination for a beach vacation at the end of July. Can't be any more south than North Carolina as we will be driving.

Places we have been that we love- Tybee Island, GA Sanibel Island, FL, Cumberland Island GA, OBX, NC.

Places that we liked but don't need to go back to/looking for a different vibe- Maine, Vermont

We like to ride bikes, go to the beach, eat at restaurants, go to little shops, see tide pools, go on nature tours/ boat rides, kayak

Thanks in advance for any recommendations
