Hi all - we're planning to rent a car next weekend and head away for a few nights. We're new to Switzerland and haven't seen much. We did a little last summer around Milan & Lugano, but only really for a day. We're in 3 things about this
1) Head north - so leave Zurich and head north ... Rheinfall, Konstance around that area, and maybe into Germany. Also maybe hit some German shops

If we were going this direction, where else are highlights?
2) Head south - down through Luzern, Lugano, Locarno into Italy maybe around Como. Also maybe work on our tans
3) Something else - head in another direction (vague eh!) and see some other highlights, that you good people might point us towards
In general I think we're into seeing some nice scenery, and if possible finding nice places to chill and maybe even some sunshine ! Also, don't want to be doing insane amounts of driving. Probably looking at c.500km in total give or take. Will prob have a car from 5pm Friday to 5pm Monday
Any suggestions - I think we're going to do ALL of these 3 at some stage over the coming months, I think it's just a question of which we do first!
Cheers
Graham
