Cosmos is the budget arm of the Globus family of tour operators. We've gone on a couple of trips with them and have been very happy with the itineraries, the quality of the guides, the quality and location of the hotels, and their level of organization. The prices are excellent, and very often a better value than going on your own (and they allow you ample time to be on your own so you don't feel tied down to your group). Many different travel agencies (online) offer 10% discounts off the advertised price. Once you've traveled with them before you often receive discounts on future tours. We would recommend them to anyone. The hotels are "tourist" quality --- not luxurious but comfortable and clean.
