We love the beach and boardwalk and shops and restaurants in Rehoboth! We particularly recommend Zoggs restaurant, Kohr Brothers' Custard, and Funland.
We go to Bethany Beach several times a year! Bethany is a smaller beach town and parking might be easiest here! There are lots of shops and places to eat. We especially recommend Mango's and coffee from Maureen's Ice Cream.
In addition to having a beach, Lewes is a historic town with shops and museums as well as lots of great restaurants!
These outlets sell everything and always have big sales!
