I have read the various suggestions for ending your trip when you return from Prague, as well as your comments on interests:
<<"I’m not much of a hiker, but being there surrounded by the beautiful scenery, I can definitely do! I love walking!
“Visit the old towns in cities that were never bombed out in WWII? Interesting!!! Yes! Historic buildings?” Definitely!!!
Museums? I usually include a few in my travels, but this time it’ll be a short stay in the cities, so I’d rather not. Unless you recommend a couple of great ones in the region I’m covering.
Eat and drink at deluxe restaurants? Spend money? ( The last one is easy in Switzerland).">>. We are trying not to splurge, but I know this will be difficult in Switzerland. Definitely, we want to try the cheese, the chocolate, wine and all those delicacies. Oh and maybe doing a bit of shopping (watches, not just restricted to the high end brands, but also something unique/different is what I’m looking for) Suggestions are welcome! ">>.
I think we have dealt with interest in walking in beautiful scenery by fitting in a trip to the Jungfrau region. Based in Interlaken, if you klike. Interlaken is a good transport hub, wirth excellent mainline rail connections. The rail lines from Interlaken into the Lauterbrunnem Valley and up to the various viallges and mountains already discussed are where the scenic walks are...lots, with different degrees of difficulty. Although we often recommend staying in one of those locations, instead of Interlaken, it is because the entire experience and ambience really showcase high Alpine Switzerland. But, the trains and other transport in and out and around the region close to the Jungfrau are not fast, and you can eat up as much as an hour going in or out.
There are nice old towns in Luzern an, actually, in a couple of parts of Zürich...near the Lindenhof and near Neumarkt on the other side of the river in the Niederdorf. Although each of the obvious cities near and including Geneva ( Lausanne and Montreux) have some older parts, and Montreux may have the widest range of easily accessible tourist sites among those three, I'm not sure that they a re known for their old towns. Geneva has a lot of "City that has older buildings as well as newer ones" if that distinction means anythingbeause I'm not sure how to express it. But, the centers of Luzern, to reasonable degree-Zürich, and especially St. Gall and Bern, all have a more distinct "Old Town" typically where the walled and/or moated cities were in earlier days. Some of our colleagues from the French-speaking region may help by refining my comments, particularly about Lausanne, Montreux and Geneva.
In Luzern, the Jesuitenkirche is wonderful. So is the Fraumünster; old, and with Chagall's art added. . See attached picture of the Jesuitenkirche at dawn.
In Zürich, if you eat in the Zeughauskeller or zum Kropf, you are in very old buildings.
Aspecial old town, with wonderful historic buildings is St. Gall. As I said before -
St. Gall ( Sankt Gallen) (watch the spellings) is a favorite of mine for
a nice old town, the Abbey library, and a 700 year old restaurant. If
you would like more details, I'll be pleased to explain. I did not
recommend it before, because I did not understand that you were
interested. Note that the timetable tells me that it is 1hr 2 min or 1hr
9 min from Zürich main station.

Museums -You will find world-class museums all around Switzerland.
Zürich has some of the best. You can read about them here:
www.inyourpocket.com/z urich/Sightseeing/Muse ums?&p=1
Scroll down to the second or third page. I'd pick the Rietbeg for the special art collections, and the Landesmuseum ( Historical Museum) near the main station
In Luzern, 3 minutes from the main station, is the Sammlung Rosengart ( Rosengart Collection). A very powerful ad extensive collection of Picassos, and about 100 Paul Klees in chronological order.
For the shopping and restaurants of all kinds, any large city will do. Zürich. Luzern,Bern, the trio of French citeis discussed.
In Zürich, the Zeughauskeller is a placed frequented by locals, businessmen, bankers, and tourists of all kinds.
Food is good and the atmosphere is fun. Close by, I like Restaurant zum Kropf. Old Switzerland.
The hotel that I stay at in Zürich, the Adler, has a very very very popular restaurant called "Swiss Chuchi) with a range of fondues and raclettes.
In Luzern, my go to place for a range from simple and cheap ( by Swiss standadrds) to good full meals, is the Rathausbrauerei. (Rathaus means council house or town hall).
I also have liked the Schiff, for years, under the arcades near the Rathausbrauerei. Used to be a hotel and restaurant, now just a restaurant.
Both places have lots of outdoor seating by the riverside in warm weather.
Zürich is my favorite city in Switzerlad. That is for culture, restauarants, and easy access tothe woods and hike on Uetliberg. Trams are terrific.
Scenery is not a special feature, which is why we send people first to Luzern...it has a bit of everything.
By the time that you return from Prague,you will already have experienced a lot of terrific Alpine scenery. So, it could be time to explore Zürich. You could spend the day just in Zürich. It would provide the shopping and eating experiences in a really nice city, with some "old town " sections to walk in. The Zeughauskeller and zum Kropf are in part of the old town.
Those who have beenon this forum for a while know that I am not a fan of the Rhine Falls.
Since you are from the US, you may have seen the US and especially the Canadion Niagara Falls.
Compared to them, the Rhine Falls are powerful, but not as hgh and notas as scenic, inmy opion. My attitude is tha I can see wateralls everywhere in the word, so I'd rather spend my time inSwitzerland seeing things that are more specially Swiss.
Just my opinion. I'd vist Stein am Rhein ( fullof tourists, syill nice) or St.Gall...but it is abit far away for your available time. Or, spend it in Zürich.
You'll have enough to do. ;-)
