Best advice is to not worry and enjoy the trip. Although there have been a few discussions on the forum recently about people getting in trouble for taking photographs in public, to look at the bigger picture, these instances are still incredibly rare.
If you tell us when you are getting back, if we don't hear from you the next day, we'll call the A-Team.
