Board the train to Dresden, then stretch your legs on an orientation walk with your leader. The afternoon is open, so you might explore the rebuilt Old Town, pass Frauenkirche, Zwinger and the grand Neumarkt buildings, or sit down for Saxon classics such as sauerbraten-style roast beef and potato dumplings.
If the weather is kind, a cruise along the Elbe gives you a softer view of the Baroque skyline. Later, consider heading into Neustadt, where street art, independent bars and a creative local scene show Dresden's less polished, more playful side.
