What's your opinion on traveling with mp3/iPod audio tours (Rome/Vienna/Venice)?
We're taking a bunch of Rick's self guided tours (and some others)for Rome and Venice, and Vienna makes the official tours you would buy at the palaces, etc available free online.
Anyone used these? Thoughts? Does it get a bit dry after a while?
Any Specific places you would get a guide for in Rome/Venice/Vienna?
We're doing a couple non-self-guided tours in Salzburg/Slovenia, but I thought one or two more guided tours might be nice.
