I'm starting to think about my next trip to Europe and am narrowing down places to go and when. I'd like to go on a longer trip (suggestions welcome for length) and do France, Spain and Switzerland but I'm thinking that might be too much in one trip. Possible dates to go would be between April and October of 2010 or 2011 (again, suggestions welcome). I'm interested in architecture, scenery (general outdoors- hiking, expoloring, etc.), but not so much into art. I'm in the very preliminary planning stages so any advice or suggestions would be helpful. Thanks!
