I've visited more than thirty times but have always avoided Crete and Corfu.
I'm now much more restricted by flights because of where I live but know nothing about either of these.
I loved Parga, Paxos, Stoupa, Skopelos..... any suggestions for somewhere similar on Crete or Corfu? Travelling alone, like a good selection of tavernas and bars, little winding streets. No high rise buildings!
