Good morning, Pets are not allowed on board Madrid City Tour, the exception would be guide/medical assistance dogs providing documentation before boarding the buses. Kind regards

Si, quando ne ho usufruito io, si poteva scendere e risalire su qualsiasi bus ed itinerario.

I don't think this metro airport bus station is one of the hop 0n hop off bus station. You can buy the ticket directly with the bus attendance. If you book in advance on website you may save a few dollars. The ticket is based on calendar date. You can get on and off as many times as you want during the day. There is extended route bus stop that goes to Madrid soccer stadium and other places which you need to pay a little bit more just tell the attendnace that you want to pay for the extended route on the date that you plan to go.

24 Hour pass. But when you're searching maps and asking people to help you find the bus stop - those hours get eaten up. When you find the stop and the bus doesnt show up for an hour - well you get the picture.

It is a calendar day. I strongly recommend the 2 day pass. This way you can do one circle trip one day and the other circle trip on the second day.

The wait depends on the season I went during summer when they said is less “crowded” it took us 10 min to get in the bus so it wasn’t bad, the places around are so busy and interesting that u can’t help being noise and look at what’s going on lol time flew by.

Hola, no es necesario reservar, lo puedes comprar el mismo día, pero te aconsejo que entres a la página para asegurarte de que trabajan el 25 de diciembre que es feriado. Te aconsejo que lo compres vía web.
