Q. Distance from Penn Station to convention center? Is it walkable?
I believe you mean 30th Street Station which is where Amtrak trains come in. Station. Instructions on how to get to the Pennsylvania Convention Center are below:
If you take Amtrak to Philadelphia 30th Street Station, do you just use that ticket to transfer to the local train?
You are correct - use your Amtrak ticket. Amtrak takes you to 30th Street Station. From there, you will need to switch to the SEPTA regional rail platform and take any eastbound SEPTA rail train to Jefferson Station (formerly called Market East Station). You don't need to buy a SEPTA ticket, just be prepared to show your Amtrak ticket to the conductor if asked. At Jefferson Station, follow signs to the Flower show -- you can enter without exiting to the street -- it's right there!
Hope this helps and I will ask our web person to put this information on this year's web site.
Thanks and enjoy the Show!
