Thanks George - it's good to know that there are other options opening up.
I've never stayed at the Plakias Bay, but did go there for lunch a few years back (we were at the far end and it started to rain, so we thought we'd risk it) We had a fantastic meal, and were very impressed with the restaurant etc.
I would like to stay there sometime - even though it's a long stagger back from Ostraco!
