In case you missed it, here are the tips from Facebook and twitter this week:
Google something you like to do and the city you are visiting: "cooking class", "hiking", "biking", etc - you'll get options that locals and tourists enjoy
When leaving magazines on the airplane - tear off your address. Don't need strangers knowing where you live.
On your luggage tag - put your cell phone - not your address. Inside put a sheet of paper with dates on where you'll be.
If you know you'll be bringing back liquids - bring wine skins with you. They are cheaper in bulk and offer great protection.
