Go to Greece!

Air of departure on next Saturday midnight I booked to go to Greece!
I don't believe I have a chance this season.
I bought a book of Chikyu-no-Arukikata on Greece and perused it.
I'm trying to reserve hotel now but the hotel I would like to stay is filled I confirmed.
I booked flight managed by Air France and this is first time to go Haneda international airport!
The only concern is transit in Charles de Gaulle reserved two hours.
But it's not vacance season yet not so many visitors are on line of immigration clearance.
Now I'll start to pack my travel luggage!
