1. Great Wolf Lodge Pocono Mountains: Scotrun, PA (85 miles from NYC)

Great Wolf Lodge in the Pocono Mountains recently underwent $12-million property-wide renovation (including revamped rooms and new attractions).

There’s also a wave pool, lazy river, and two hot tubs.

Linger longer at the rustic, log-cabin-style retreat and stay in one of the 401 revamped, woodsy themed family suites. When you need a break from the water, explore the newly added attractions, including Oliver’s Mining Co., an immersive, mining-themed educational adventure. Additionally, you’ll find updated food, shopping, and beverage offerings. Rates from $179 per night, depending on the season.
