1. Chester: The Glenmere Mansion
From NYC: 1hr 15min by train
If you want to feel like royalty for a weekend, stay at this Hudson Valley hideaway where legit kings and queens have rested their heads. That's right, this adult-only country estate was once a private retreat for members of the royal family. There are only 18 rooms and suites—and a grand piano player willing to take requests—so you'll feel as if it's your own private mansion. 634 Pine Hill Rd, Chester (845-469-1900, glenmeremansion.com)
