We are just back from Plakias after a 2 week stay and I can now answer my own question.
Firstly, the weather was good for early May with just one afternoons rain and that on the last Saturday of our stay.
But early sping in that area has been very dry and much of the wild flowers we went to see were past their best.
The sea was cold (ish) and fairly rough for much of the time but not too rough to prevent swimming and the wind was never strong enough to drive the sand along the beaches to make it uncomfortable for sun bathing.
For the fist week, the beaches towards the far end were very quiet, with few takers for the sun beds.
It may have been us, but there did seem to be fewer English visitors there this time with more German and others but this may just have been our take on things.
As for prices, then we were very pleasantly surprised by what we found.
The main increase was on petrol and the cost of a litre now at about 1.55/1.60 euro which is a very big increase from last September.
The other big rise was on alcohol (metaxa) and wine.
The new tax rises have increased the prices but not by the same amount in all places, so shop about.
But as an example, we paid at Chania Airport 20 euro for a litre bottle of 5 star Metaxa to drink on the cold, wet winter evenings in Yorkshire.
And that was just about all the bad news we found.
Cost of meals in Tavernas was very much as we remembered and Supermarket prices to not seem to have changed very much.
Two very good weeks holiday with no problems or complaints.
We will just now have to wait for the 14th September for our next visit, and it can not come quickly enough !!
