U2 have already told their fans not to believe any rumours about forthcoming tour dates until officially announced, but try telling that to hoteliers in Dublin.
Speculation is so rife that U2 will play the city's 82,000-capacity Croke Park on three consecutive nights of 24-26 July, that the neighbouring Jurys Hotel in Dublin has now tripled its prices. Rooms are now selling at €299 per night for a superior bedroom compared to €99 the previous weekend.
Jurys' general manager Edward Stephenson stressed that supply and demand issues had led to the price rise with the hotel already 85pc booked up.
"We have very high occupancy here for those dates," Stephenson told The Irish Independent .
"We have very little availability left so that would be the normal situation in a hotel that we would sell off rooms for a cheaper price first.
"A number of people have got very competitive rates for these dates."

U2 release new album No Line On The Horizon on 2 March and announce tour dates mid-March.
