Austria
I have visited Austria on several occassions. Mostly I have passed through on European backpacking journeys.
As previously stated, I have visited Austria several times. Austria is part of the Schengen Zone in Europe and therefore does not require a visa for trips of 90 days within a 180 day period.

While there is a variety of ways to avoid additional fees while traveling - I have personally found the Charles Schwab Investor Checking to be one of the easiest and most straightforward accounts to utilize on the road.
