Had a great trip organized by the Euroventure team with me and a friend! They quickly organised it for us pretty last minute, even accomodating our requests for alternative travel methods and order of cities (my friend hates flying). One of our hotels was even a 5-star one, even though we had only booked the 3-4 star package. The little booklet they give your is also super handy with phrases and recommendations. My only criticism is the delay of response I got when looking into a second trip with them a year later. I had asked a question regarding timing and reordering of things and no one really ever got back to me. I ended up planning it myself.
