After arriving at the Port Authority my father and I set out for 30 Rockefeller Center, since while I was given ticket reservations I wasn't given actual tickets and who could tell when the tickets would run out? For that matter who could tell when the line for actual admission had formed, and when it would have the magic 210 people that fill the studio in it? We set off looking for the sunny side of the street since the weather was below freezing and extremely windy and discovered that the sunny side wasn't actually warmer by any appreciable measure. At Rockefeller Center after some looking around for the elevator where people used to line up for Late Night back in the 1990s we found NBC pages who told us, very distinctly, that the line would form about 3 pm in the mezzanine level and there we'd be given tickets and wristbands to attend the show and we should not come back before then.
Considering the people lined up for standby tickets overnight I figured, well, perhaps we could try to be back for 2 (for a 4:15 official-lining-up and 5:30 start of taping) and if that went wrong, it would just go wrong. We set out with my father's vague plans to go to the Metropolitan Museum of Art (my parents are members) and we started out dashing quickly to Saint Patrick' Cathedral which is quite nearby Rockefeller center and also fully heated. The cathedral has been retrofitted to be reasonably wheelchair-accessible, I noticed, except that the entrance doors are those imposing type which weigh about as much as the Twelve Apostles combined. Accessibility is an evolving thing.
From there we went east a couple of avenues' worth, stopping only for the NBA Experience Store where we thought there might be something intriguing or at least novel or maybe some spot where people could embarrass themselves by playing at being basketball players. If there was we never found it, although they did have Real Basketball Player shoes which were very nearly large enough for 
tracerj's needs, almost. Also the revolving door entrances have as handlebars brass-like fixtures which look like a player's arm with a chunk of basketball so that going in is like bumping into a hydra-armed decapitated professional athlete. I'm not sure that's the experience they were going for.
