For a variety of reasons, I'm looking for travel companies that pre-package vacations. I do all the arrangements for domestic vacations, but I'd like to branch out to Europe. I have no idea who is good/who is shady, and some of the places I'd be interested in seeing I don't currently speak the language (so I'd want someone else to do those arrangements). Specifically, I'd like to find a company that organizes hiking/walking vacations whether that be with a guide or just with instructions and hotel reservations. But I'm not limited to hiking. I'm just looking for a rather active trip with perhaps active/curious participants rather than just sitting on a bus for a week or two with dull people.
I know about Road Scholar, and Vermont Bicycle tours (who just bought Country WAlkers). What else is out there that is reputable?
