Hi everyone,
I am going to be going to New York and arriving in LGA at 11:30PM. I am going to be meeting my family there but they are arriving in a different terminal at 10PM. I will be arriving in terminal in terminal D and they will be arriving in terminal B. The website says that the shuttles run in between terminals till 11:30PM. I was wondering if I were to walk and meet them at their terminal, are there walkways connected inside the airport, or is my only option to walk outside? Also I was wondering if there are separate baggage claims at each terminal, or if there is one baggage claim where we would meet? Is this a 24 hour airport, meaning at 12PM it won't be really empty? I'm a little scared since I'm travelling alone and it will be late at night. I was travelling in Miami at night and there was absolutely no workers at 11:30PM, I didn't have anyone that I could ask for information, just hoping that doesn't happen again. I'm thinking that they could meet me at my terminal but they also want to know about the questions I'm asking.

Thank you in advance!
