Bratislava turned into my favorite city on my trip this summer. It has that old world european feel, but because most do it as a day trip from Vienna the streets are relatively tourist free in the evenings/night.
We stayed at the Park Inn Danube, which was only 9,000 points/night. Quite a value if your a Club Carlson member. Our three night stay was only 18,000 points because I have the CC visa and get the last night free. Our room was SO nice, probably the best on Carlson hotel stay on our trip.
Bratislava has a couple must see attractions like the castle and the blue church. The rest of the time you can while the day away drinking the interesting lemonade combinations that every restaurant has, and take photos with the sculptures that are scattered around town.
