The Spurs' centre-back believes he still has a chance of making England coach Fabio Capello's 23-man squad that will travel to South Africa for the finals that start in South Africa this June.
"I've not booked my holidayss yet," Dawson has said.
"My wife keeps nagging me and asking me where we are going.
"I might not have decided yet! Even if I don't get selected for the World Cup, I'd be watching every England game anyway.
"It's a dream to play for England, I was a sub a few times but never got on the pitch. Winning an FA Cup, finishing fourth and going with England would be everything.
"People say what do I have to do - I say if I keep playing well I will have a chance."
