Head to the Riverfront for a walk along the river, a coffee at Starbucks, a delectable margarita at Del Pez (we recommend the infusions!), a beer at Iron Hill, and more.
Visit the Delaware Contemporary at the Riverfront (free). It's a great activity for Saturday before the wedding or Sunday before you head out of town.
Longwood Gardens in Kennett Square, PA is about twenty minutes from the hotels. It's a beautiful massive DuPont property with a conservatory, acres of gardens, and DuPont family homes.
Visit this nearby town for breweries (like the Creamery, Victory, and Kennett Brewing Company), good food, and cute shops.
Visit the Delaware Art Museum in Trolley Square ($12). It's a great activity for Saturday before the wedding or Sunday before you head out of town.
Best coffee, pastries, and breakfast sandwiches in town. It's small, though, so you may have to wait if you don't just want coffee and pastries to go.
