Hello
I absolutely do not agree with newnoise at all. You do not need to bypass Switzerland just because it might be little more expensive than Austria. There are so many reasons why you should travel in Switzerland:
Nature, Water, Public transportation, four cultures, traditions, sports, events, health, cities, hospitality and QUALITY!
Campsites are not to hard to access at all as public transportation is so well in Switzerland.
Here are three links where you can find affordable hotels/hostels and bnb's.
ENJOY SWITZERLAND
