Getting there
Where it is, how to reach it, and what to do with the car.

The venue
We are getting married at El Antiguo Convento, a restored 17th-century Carmelite convent in Boadilla del Monte, just outside Madrid. The ceremony is in the church of the Convento de la Encarnación, next door on the same street, and it is a minute on foot from there to the drinks. Once you arrive, you will not need the car again all day.

Bus
Yes, we are putting coaches on. They leave Madrid in the morning in time for the ceremony, and come back to Madrid when the party ends, around 11 pm. [To come: where in Madrid they leave from, and the exact times both ways.] If you are coming from Madrid this is by far the easiest way, because then nobody has to drive home.
Parking
The convent has no car park of its own. You can park on the street in the old town, or in the municipal car park on the Plaza de la Concordia, which is in the same old town and is free from 10 am to 8 pm (after that it charges by the minute). Since the party ends at night, the coach is the better bet if you are coming from Madrid.
If you're travelling in
Boadilla del Monte is about 20 km west of central Madrid, half an hour by car and longer in traffic. Fly into Madrid-Barajas; trains arrive at Madrid-Chamartín or Madrid-Atocha. [To come: driving times from the cities most of you are coming from.]
Taxis
Uber, Cabify and Bolt all work in Boadilla. When everyone leaves at once they take a while, so order one in good time, or better, take the coach back.
