We’re planning a vacation this summer to the DE area and trying to decide between Rehoboth and Dewey beach or somewhere within the vicinity. We prefer to be within a 4 hr. drive of the DMV area since we're leaving the kids behind (Yay!!!). We’ve never been to the area so we're not exactly sure where the best places to stay would be. Since we’re traveling without the kids, we're looking for a combination of relaxation & nightlife options and definitely a diverse population. We're in our late 30's so we would prefer not to be surrounded by mainly 21 yr. old's, but we also like to have fun! We do know that we'd like to be within walking distance to the beach (possibly the boardwalk), restaurants, and water activities. We are thinking that a weekly vacation rental would be best rather than a hotel/inn, but we're open/flexible - and we definitely want a place that has a balcony/patio/ outdoor access from the rental. We would like to keep the rental cost under $1900 - $2000/week if possible/realistic for what we're looking for.
What are some suggestions/recommendations/advice on the best locations that would suit our needs as described above? Also, what are the differences between North/South Rehoboth, Rehoboth by the Sea and Dewey Beach?
Thanks in advance!
