The tourist attractions are tourist attractions because that is where the sights are.

Rome is a very large busy city. I’m not saying don’t go there, but a smaller city like Florence has more to see in a smaller space.

From Venice, take a train to Tirano and from there to Chur. They have an expensive tourist train (the Bernina Express) that runs this route, but the plain train runs the same route with the same great scenery. I would overnight in Chur, then catch a train to Luzern via Andermatt, more great alpine scenery. I split the rides because it is quite long and you can’t see the scenery after dark.

Interlaken is very touristy, but everything in that area is. You might rather stay in Lauterbrunnen for better scenery, or at http://www.mountainh… for the best scenery.

Bern is a more staid city with a lot of government offices, but has some interesting things. You might consider Thun instead as it is smaller and has a nice old town.

I would definitely try to include Rome. There are few places where you can see and experience so much staff that’s important to our history and culture in three days. Rome is swarming with tourists, but Rome loves its tourists, which makes the experience of being a tourist enjoyable. It’s busy, but I think in a “fun” way. By contrast Milan, IMO, is much more “just busy.”

Thanks! All great advice.
