I did two half-day sessions with Konstantina--one at sunrise and another at sunset. I chose to do them on different days. Net-net, I got some great shots that I most definitely would not have gotten on my own. Konstantina got me to the right places at the right times--both being critical. Two favorites are sunrise at Koloumbo Beach and a more classic (i.e., also touristy) view of blue domes in the foreground and water in the background. The buildings in Emporio were also a target-rich envirnment. Both tours with Konstantina were well worthwhile...strongly recommended.
