Thank you sooo much for letting me know that!
Unfortunately, this hotel has no shuttle bus service…
I’ve called the hotel last night and if taxi is available 24hours, then she, front desk, said it’s available 24hours and is going to call for a taxi for me.
I’ll keep that in mind Philadelphia is not like NYC. So, I will make an arrangement for taxi in advance. To catch my flight 9am departing from NY (LaGuardia Airport), I need to get there before 7am.
I’ve also asked her which is safer Grayhound station or Amtrac station in the midnight, and she told me Grayhound because more people are there than Amtrac station.
