NYNY left me pleasantly surprised! I've only stayed for one night with my coworker but it was a really good experience.
Our room was far from the elevator, so it was quiet and left undisturbed. Yes, there's a roller coaster outside but it doesn't really affect your sleep.
Although NYNY seems like a rowdy casino/hotel downstairs, with children running around and all...the hotel itself was really clean.
My only standard for hotels are its cleanliness and easy parking. NYNY has met all of that. I'd definitely consider coming another time!
