Reading could go two points clear if they win their two games in hand while Birmingham and Cardiff can draw level with Mick McCarthy's side if they take advantage of their rearranged fixtures.
The race for promotion to the Premier League is wide open and McCarthy is hoping a four-day break in Spain will take the heat off his players ahead of Sunday's crucial encounter against the Bluebirds at Molineux.
"It might be viewed as a negative by some people thinking we're going away for a jolly but that's not the case," he told the club's official website. "I think it's a good time and the players have earned a few days away from it all and I am sure it will do them good.
"We've got a young squad and to go away and have a bit of downtime and relax as well as do a bit of training should galvanise team spirit. We can then come back refreshed and resurgent for the next 13 games and hopefully feeling better about ourselves."
