Congratulations, Chad.
All three NYC airports have good options for transportation into midtown, but LaGuardia (LGA) is the closest. Cabs can be pricey, but buses are available (and, from JFK, there's the AirTrain--an elevated train loop around the many terminals that also connects to the NYC subway system, so for $7 you can get from any terminal to almost anywhere in the five boroughs).
The hotel where ABC put us up when I did the show is closed, unfortunately, but there are plenty of
others in the area; several are in walking distance of the studio. You might want to try
TripAdvisor, too (I've put in some wild-guess parameters, but you can adjust those to your liking.)
Good luck!
