1. Avoid the queues
This tip is my favorite. There is nothing as frustrating as wasting your precious time standing in the queue to see this or that place. You can always avoid the lines if you purchase tickets in advance. Buy museum passes, bus or train tickets beforehand. There are even multi-passes available. It means that you will be allowed to enter a few museums without standing in the lines. You can do this either when you arrive at your destination or, which is even smarter, do it online from your own home! You will save a lot of time and spend it on sightseeing rather than on boring queuing.
