Hi, can anyone recommend some things to see or do in Vienna with less than 24 hours? I've looked at a few tourist companies, but most of them seem to end by the time we arrive or the tours are too long to do in the morning. We'll be getting in around 4:30PM and our flight leaves at 1:00PM the next day. We'd like to take advantage of our long layover by touring the major attractions, but with so little time we don't know what to do. Any suggestions would be greatly appreciated!
