Thanks everyone!! Looking forward to my trip in May.

don't know if I asked this on another thread but what are your dates you will be in Prague.I will be there from the 22nd- 30th May for the Czech Beer festival.

It stars on the 16th May and goes on to the 1st June
well worth a trip there one evening, not just beer available but all sorts of drinks including soft drinks, some good food and live music, can be a nice cheap night out and a taste of real Prague culture.

We will be in Prague for a few days in early May before our Danube cruise. We'll be staying at the Hotel Art Deco Imperial with the rest of our tour group but will have some time on our own for exploring and meals. The Prague websites above will be helpful to us as well. Thanks.
