I don't see how people flying to the Resort is anything to do with PortAventura themselves, plus the Resort is located in central Europe, so I'd imagine most people will arrive via cars, trains, buses as opposed to planes.
Hotel Colorado Creek is also the Resort's first 0 emissions hotel with the others being modified to follow suit in the future.
Staffing has definitely increased across the parks, in previous years 1 staff member would do the job of about 3 people yet this year has improved. For example El Diablo would previously have had 1 operator and 1 person batching and checking restraints. However at the moment there is 1operator, 1 batching and 2 checking restraints. I've taken photos because obviously I've made it all up.
