So I think I am going to try to swing by the Porsche Museum in Stuttgart as I head back to Frankfurt. It looks like I will only be able to spend around 2 hours there given the train schedules and my schedule. I'll need a place to store my luggage at Stuttgart Hbf, wondering if it is lockers or if it is like the setup at Berlin Hbf. From what I can tell by the station layout is that it must be lockers and that they are located about everyother track. Is anyone able to verify this? Also, would there be an issue from taking a backpack into the musuem (regular everyday backpack)?

At this point on 3/14 I tentatively plan to take ICE Munich-Stuttgart, S-Bahn to Porscheplatz and back and then ICE to Frankfurt via Mannheim. DB prices this out all on one ticket, but I am curious how will the S-Bahn portions be handeled when I get my ticket? Are they ticketed like the rest of my legs or is it in the form of a city-mobil ticket or ??

Also, any recommendations for hotels near Frankfurt Hbf? Have a few in mind, but would'nt mind hearing what everyone might recommend...

As for heading to Garmisch/Zugspitze, I am going to leave that to be an open question to be setteled when I wake up on the 13th. If I get up early enough and the weather looks good, then more than likely I will head on down there and get back to Munich in the afternoon.
