Rudesheim was fun. I went to the Music Museum with fairly low expectations but it was OK and only went for 30 minutes anyway. The only issue we had was that it was a hot day and the place is not air conditioned. After the museum we wandered around the town and came across a summer wine festival in the town square which sated the thirst nicely.
The included tours are, by their nature, only a brief introduction to the town or city. Ideally, if time allowed, we went on the tour in the morning and in the afternoon went out by ourselves and explored a bit further and at a gentler pace that allowed for a wine or beer along the way as well as some shopping. The brevity of the tour is obviously more of an issue in cities where you only see a fraction of what the city has to offer and we came away from places like Vienna, Amsterdam and Budapest wishing we had had more time.
