Which NYC landmarks are frequently featured by Mommy Poppins?

I'm sorry, but the documents provided don't mention specific NYC landmarks that Mommy Poppins frequently features. However, they do mention the New York Transit Museum as a favorite family fun spot to visit with kids in NYC, and a memorable holiday experience at @citypointbklyn known as the Holiday Hub. Mommy Poppins seems to focus on family-friendly activities and locations. If you're interested in more specific landmarks, I'd recommend checking out the Mommy Poppins website or social media pages for more information. Is there anything else you'd like to know about?
