I would like to wish the travel agency to think about the night sludge of buses. The issue of transport for sightseeing tours in cities during heavy rains (even if for an additional fee) was not thought out. It was very unpleasant when in Berlin the bus dropped everyone off in the pouring rain and left to settle for 9 hours. You don’t spend a lot of time in the puddles, and all the sights are not to your liking.
