<<" if we start around 8 from Bern, will we have enough time to see both Greyeres and Vevey towns? We will be going to the cheese factory in Greyeres and the castle, can we also hop off in Vevey and see the sights? ">>
You can get those answers by working the timetable and checking a map. The name of the town is Gruyeres.
I do not recall any sites in Vevey that would justify a detour.
There are some in the mountains above:
Arno gave you the link for the timetable.
Here is a good map. This map is particularly useful for Swiss travel, because of the information available from the menu choice of "Points of Interest/Traffic."
<<" also this particular day trip will fall on Aug 1st monday and i read somewhere that its National holiday. The chocolate and cheese factory seem open. Will typically all shops restaurants be closed around our train route? I am assuming we can hop off hop on in between.">>
You have raised a good point. I have traveled around Switzerland on August 1, and found, especially in the smaller towns and villages, that everything was closed. Hard to even find a sandwich. Big cities are likely to be OK, and places with heavy tourist traffic , as well.
Arno and Annika might have a better perspective than I....it has been a long , long time since I went to Switzerland at the height of the tourist season in August.
<<"Thanks Slowpoke for your Montrex suggestion. I had considered that and Vevey as well but thought Bern is better for travel to Munich. ">>
<<" Agreed. I only mentioned in case you had not considered it. ">>
<<"Might see Bern city in the morning after checkout.">>
It is a lot more attractive city for a quick tour, in my eyes, than is München. The old town is not terribly large, and is very attractive. No equivalent of the Victualienmarkt, but plenty of places to grab a bite, and the Old Tram Depot near the Nydeggbrücke could be a substitute.
<<"Also Interlaken is 45 min only from Bern, on day 3 we could stop at Interlaken while going to Bern. Can we keep luggage at interlaken station? What can be done in a couple of hours there?">>
If you go from Luzern to Bern, it takes 1 hour on the fastest trains, 1 hour and a half or so on the other frequent trains.
If you go from Luzern to Interlaken to Bern, without stopping, it takes 2 hours and 47 minutes.
Interlaken has very little to attract a tourist, other than accommodations and a good set of rail connections.
To see anything really special and worth the detour, you need to go to Grindelwald or (my favorite) Wengen , which adds a half an hour or 45 minutes each way. A ride up to Schynige Platte from Wilderswill might be considered, but it is time consuming. Might check Harder Kulm....I have not been there.
Use that map. Zoom in a lot.
We are now daling with personal opinions, and others may feel differently. If so, I'm sure thatthey will comment. ;-)
