We joined early August and have booked via a travel agency. We had some friends that have joined on June and did not have a nice experience and we were a bit skeptical. Likely enough our week was great. The parties on the islands were awesome, we met new friends and all bonded from day 1. Breakfast was basic, but meals were nice even if they did not cater for vegetarian. Do yourself a favor and follow the Quad safari as by far was the best day for us. Yorgos knew all the hidden places and everyone enjoyed it. The BBQ at Ios was a plus but you had to pay for transport to get there. Apart from that we had a nice time.
