"Must see" would include: Semper Opera House, the Zwinger, Pillnitz, City Palace and the wonderful porcelain collection. The Frauenkirche (Church of Our Lady)is being restored with contributions from around the world. It was the largest Prostestant domed building in history.
Quick Tips: There are several walking or bus tours of Dresden. I always find this a good way to "get the feel of the city" before setting out on my own to explore. Walking tours cost about DM12,00 and bus tours can run from DM18,00 to DM65,00, depending on length and area covered. I especially enjoyed the Classic walking tour which lasts about two hours.
