Keep a mini notebook in the front pocket of your bag or in your pocket, it doesn’t matter where as long as you can get to it easily. Before you leave for your trip fill the notebook with details of where you are staying, contact telephone numbers and any other bits of information you may need whilst at the airport and for when you arrive. It’s good to have a hard copy of all your travel details and destination information. I like to keep a note of contact telephone numbers from home and anyones addresses who I may be sending postcards to. I also spent some time on Sunday adding addresses of diners I want to visit in NYC, opening times of museums and a few others bits of key information I may need whilst on the go in the city.
