Great Question? Sorry I don't have any suggestions for the NYC area, but it would be nice if members would suggest any good cat 1-4 hotels in other cities. There are some good cat 1-4 in the Los Angeles area. Torrance Marriott South Bay, very nice, walking distance to restaurants, bars, shops, close to Redondo Beach and Hermosa Beach. SpringHills Suites Los Angeles/LAX/Manhattan Beach, also very nice. Also the Courtyards in the Torrance area are nice.
Welcome to the Marriott Rewards Insiders community. Two properties that you may consider:
Westchester Hotels | Renaissance Westchester Hotel - this is currently a Category 5, but is scheduled to drop to a Category 4 on April 8
