Ah, this Texan is green with envy.......

We are waiting to see how Patti is during that time frame. It would be so nice to visit Vienna and see two Wildclickers at the same time.

I'm not holding my breath though - Patti has not been doing well.
Yes, Budapest and Bratislava are must see places..... And so is Sopron, Ungar if you can do that. So much to do and see - your short stay isn't enough time. Then there is Znojmo, Czech Rep (pronounced Tsniam) and/or - - - oh, never mind, a week will not allow you to make it.
I agree with hbg - the Dorotheum is fun.
You should have a cup of coffee in the Hotel Sacher - it's right next to the Opera House. Good coffee and NICE ashtrays.............
Tell us more later about your plans.....
