Lionel/anyone else - want to meet around 2pm at the statue in the Schlossplatz in downtown Stuttgart? It's just down Konigstrasse from the Hauptbahnhof.
Do you know how long it takes to do the Hauptbahnhof => Hotel => Konigstrasse ?
Anyway, if I do not have the time to check-in and come back, I would not mind go directly do some touring from the train as my backpack is not too heavy. I would just have the time to grab a sandwich and find the way to the Shlossplatz.

PS: this starts to get mightily complicated with all the different arrival times :-)
