See this little boat in the sea down Santorini hill?
There is more than a hundred islands in Greece, and some of them are hidden places where you can enjoy the best food, the best view, and the incomparable greek hospitality (you should try the genuine greek breakfast in one of these little gems).
Would that blow your mind to suscribe to a traditional greek dance class that would allow you to travel in a budget, and have some quality time?
That sounds pretty adventurous, and yet you could do it... and see what happens.
And have a fresh start once back in London.
