Thank you all so much for the help!
sorry I realized I was very vague in my post, we will be starting from sussex county to west palm beach atlantic, we have from the end of july (not 100% positive on exactly what day but I would say about july 25/26th) and then we have until august 10th, time isn't the issue because we will be staying in florida so we won't have to take the trip back up for a while so we do want to see what we can take advantage of one the way down. i do love the ideas os the islands and sunset on the beach, that is exactly up my alley of what I would love to do. or lighthouses and things like that, we love hikes and enjoying nature so I will definitely have to write those places down. My boyfriend is a history buff too so do yall know any places that are must sees for history or even any interesting stories?
I will definitely take a look more at the motels and cheaper places to stay, thank you all so much for taking the time to reply to this- i truly appreciate it
