Looking for some suggestions/help here, since I've never been to this part of the world! My wife and I are looking at a ~2.5 week trip in late August/early September...the only constraint is that we want to spend 4 days in Paris at the end (yes...know that is not the Alps), and we definitely want to spend time hiking in the Dolomites. As such, we're likely to start out in VCE and spend a couple days there (I have heard from others who have visited that it's extremely touristy and not worth a long stay) before grabbing a car and heading out and driving into the mountains.

Questions are this...

1) Love the outdoors and absolutely love challenging hikes, but we also like seeing different scenery. Is there enough variation within the Dolomites to spend up to a full week (or even longer) in the mountains? We would not be looking to camp/do multi-day hikes.

2) If that is not the case - do folks have a strong view on whether continuing through the mountains to Innsbruck (or furthermore, Salzberg) is a good idea? Looks like there is some fantastic scenery there as well, and plenty of hiking trails to boot.

3) Not strictly in the Alps - but would anyone advise on spending 2-3 days in Vienna? Seems like INN-VIE or SZG-VIE via plane is easy to swing. Vienna is a city I have had on my list for a long time, but I have not gotten around to visiting - and I figure it would be great to take the chance on going during the summer (as opposed to wintertime or early spring, which would really only be the workable choices for me in the next couple of years). Or would Munich (which is also closer to western Austria) be a better choice?

Thanks!
