So me and my friend want to go on one of those group trips to Europe this summer. My friend went last summer on a bus tour thing with a bunch of other people (most of whom apparently turned out to be Australian) across like a dozen countries in Europe and he said it was pretty awesome.Anyone ever gone on one? Also, anyone know of any sites that offer these? It doesn't have to be a bus tour, we're pretty much up for anything. I'm looking for something about 2 (maybe up to 3) weeks long cause I don't think I 'll be able to take more time off from work than that.Pic not really related; just something I took when I was in Paris last Fall.
