I have a three week trip coming up in July, and I'm struggling with the decision about how to get around. I think I'd really like the flexibility of having a car. I'll be travelling with my girlfriend, and our plan would involve renting a car as we leave Vienna and heading towards Switzerland with stops in Zell am See and Innsbruck, eventually ending up in Zermatt. My main concern is that the roads will be congested with traffic during July. Can anyone comment on the conditions in July or have any other suggestions?
Thanks for your time,
