After getting hitched, Humphrey Bogart and Lauren Bacall famously retreated to the seaside town of Mystic. Because you also want a town that is small, pretty, and full of coastal photo ops should the admiring paparazzi, who we are sure constantly totally follow you, want a picture of you with a good backdrop, you should head here, too. The main attraction in town is the Mystic Seaport, where you can see old restored ships and a tiny recreated 19th-century village. (You better believe they have a printing press.) There's also an aquarium, planetarium, and dining options outside that one famous pizza place. And if you're all about authenticity, you gotta book a stay at Bogie and Bacall's actual hotel, The Inn at Mystic.
Montchanin (Brandywine Valley)
Montchanin is where the very lovely Inn at Montchanin Village is based, but you're not going there to explore that town specifically (it's an unincorporated community, anyway). You're going there to drop your bags, maybe do a quick spin around the hotel gardens, and head out to the larger Brandywine Valley area. While you won't be inundated with an incredibly boozy concoction everywhere you go, the region, which encompasses swaths of Delaware and Pennsylvania, does have several gorgeous manors and gardens there, including the Nemours Mansion and Winterthur, built by the Du Pont family. You can check out those, plus the Delaware Art Museum and, like, so many parks. But if your partner has a home shopping addiction, beware: the QVC studios are just over the state line.
