I have discovered that I have less money when I came to Phuket, on 22th December. This red luggage was always with me during the flight to Phuket (it is a hand luggage), so nobody else didn't opened or carried this bag, only me. Here in Phuket, I have checked the money in order to pay something with them and I have noticed that instead of 1800 usd I have only 1100 usd, which means that 700 usd are missing. So taking into consideration all this, it is obviously that the money have disappeared in Bangkok during my stay in the hotel.
