I've gotten a lot of input, and have narrowed it down (I think) , to two options for my son's trip from Interlaken to Munich: I'd love input on which would provide the best scenery, connections, etc. for him. He's in a study abroad program and doesn't have time to research this before he leaves for Switzerland, and has very sketchy internet connection at his hostel (in case you're wondering why I'm the one looking it up) . The cities listed below are the one's where we'd need to change trains. Also, most have only a 10 minute or so connection (particularly Zurich). Will that be an issue with a big bag(with wheels), and if so, what kind of ticket does he need to make sure he won't have to pay if he misses the connection and needs to get on another train?

Interlaken, Bern, Zurich, Innsbrook, Munich

or

Interlaken, Bern, Luzern, Zurich, Munich

Doing both Luzern and Innsbrook would be too long, time-wise.

Any recommendations which would be the most scenic and/or best route for someone who hasn't been to Switzerland before, would be really appreciated.

I think both routes had 3 connections. (plus the extra s1/s8 train to the airport in Munich) Didn't even look at the cost yet Also, is 10 minutes between connections okay in Zurich?

Thanks!
