Disappointed!
We were on a Greek vacation tour. It didn't work from the very beginning. The bus was not what the tour operator stated. The guide (Vladislav Grinenko) said that we were unlucky and the bus was replaced, since the super comfortable one we were supposed to ride broke down. No one informed the tourists about the replacement of the bus in advance! The bus is old, there is not enough space, there is no climate control: it is either terribly cold or hot.
