1. The R2 train will take you from the airport to Montmeló (where the circuit is located) but it’s still a bit far. I think that for the Grand Prix the circuit is scheduling buses from the train station to the circuit (and viceversa).
2. The T10 allows you to do 10 trips, so if you’re staying for 4 days then you’ll spend 4 going to the circuit and 4 going back to the airport/hotel = you’ll use 8 out of 10 trips that this ticket has.
3. There’s a train every half an hour, and I think that for the Grand Prix there’ll be more trains scheduled for the R2 line. The last train leaving the airport is the one at 23:40
4. At the airport’s train station, there are several machines where you can buy a T10 for 2 zones.
I speak Spanish, so here you have what I think is a better translation:
After listing the battery of measures and cuts, the vice president of the Consell, José Ciscar, has focused on the big events in which the Valencian Government has put a lot of effort in recent years. Ciscar has informed that due to the exceptional situation of crisis the Consell is putting under review these big events, although he has defended their beneficial effects for the Comunidad Valenciana’s economy.
“They [the big events] are not possible in the way we have understood them until now,” he said. In that sense, he confirmed that the Consell has sent a letter to Bernie Ecclestone, President and CEO of Formula One Management, with whom the Government has a signed contract for the celebration of the Grand Prix in Valencia, to address a possible revision. Ciscar admitted that the Government is in a position of weakness because it can not cancel this contract unilaterally, because it would cause more economic problems in addition to the current ones.
“I still have not read the contract and I don’t know which impact would have the cancellation of the next Grand Prix edition,” he added. The annual fee paid by the Government to Ecclestone in order to have Formula 1 in Valencia equals 21 million euros. Also, Canal 9 [the regional channel that broadcasts F1 in Valencia] pays four million euros a year for the broadcasting rights. The construction of the street circuit cost around a hundred million euros.
