Actually Lucerne would be a great base (see Slowpoke's link for day trip suggestions, hotels and more). It's close to Zurich so your departure would be easy. Your tour may have covered Lucerne since it includes the Titlis, but I'm sure there's a lot in that area they did not cover.
But, now you mentioned Geneva. And I suppose you mean Montreux and Lausanne? So is that your plan for the remaining days? In that case you can base yourself in Montreux and do trips into the mountains and to the lake from there. Then end your trip with one night in Zurich to cover the Rhine Fall.
