How do u get the shuttle bus do u need to book so it can pick you up from the airport

To minimize your wait, you should call the hotel and ask the front desk to send the bus to whatever terminal you're at. Typically, you'd wait at zone 4 outside baggage claim, but confirm that as they've shifted some pickup areas due to construction recently.

Yes

Front desk

Just call. It runs every 20 mins from the hotel. Very easy 6 mins to the airport
