Get to see plenty. Great to know that everything is sorted and all you have to do is turn up. Our driver, the hotels, the included activities were all fantastic.
Overall I enjoyed the tour. The sights and destinations were great. Our group got along very well and that was lucky. Our accommodation in Athens was excellent. However, the accommodation during the tour was not very good. Some hotels had things missing or not working in their rooms. B.: Olympia air conditioning! We would have paid more for the tour to get better accommodation. The food was not very pleasant. The breakfast buffet and part of the dinner were inedible. Hot things are cold, cold things are hot! The included lunch was at a restaurant that does not have something for everyone. Some of us only wanted sandwiches but were only offered pre-cooked food! The "included" wine was terrible. Most of the optional tours were fine. Driver and tour guide were great.
The hotels were lovely, really nice. However, the one in Santorini, we were stuck in rooms round the back of the hotel. We had no sea or pool views like most rooms. We figured the tour company must have asked for the cheapest room.
