if you go to mamas too, suggest you walk across the street and share a slice at sal and carmines. during the chau crawl, lucalis was a favorite but you’re going to have a long, long wait. the other places, depending on what time you get there shouldn't be too bad though prince st can be tough. also the city fills up with tourists the last couple of weeks of dec so if you’re there beginning of dec, should be much easier. btw, nyc pizza suprema should be walking distance from your hotel.
i dont want to discourage you from eating pizza twice a day but nyc is a great food city, try to have a good bagel, hit katz for pastrami, chinatown for dim sum, ramen, thai in queens…the list is endless.
enjoy!
ps people underestimate how much walking we do in nyc, bring sneakers and or well broken in shoes!
