How open your complimentary airport shuttle runs from/to PHL airport

I have never used the shuttle before you can call them directly to find out the info

Used the shuttle on our stay in May. Tremendous service. SALUTE

I have used the shuttle a few times. Once you have bags at the airport, you call and then it takes about 10-15 mins to pick you up. To go back to the airport, it leaves every 30 mins or you schedule it for early morning flights.

I believe its 24 hours but you have to call to schedule it..
