This will basically annoy everybody except the ACO, I think. The teams will be ticked off because they'll have to alter their hotel bookings/transport plans etc, the press probably won't be too happy either as they'll probably have to do the same. But the people who'll really lose out will be those who've already booked time off work for next summer and whose bosses refuse to let them change their dates, along with anybody who's already booked travel arrangements and will now have to amend them. That and the hotel booking system in Le Mans will be going barmy over the next few days trying to keep up with all those altered bookings.
