Well I don't know how you call it, we call it Forma 1, but im sure you know its coming real soon. I myself am not much of a fan. (Try to live in Mogyoród since you were born and when you cant get a sleep for a week cause of the races and the after parties, you get it why. Ppl living here may like it, but mostly those who have a share from it, if you know what i mean) I mean yeah the town is whole living and lovely and everything, im just not a party girl. :P Also when i was a kid (10) i had to explain a really drunk german man, that he doesnt have a room at my house but in the neighbours. I dont speak german better now. But doesnt matter.
Here we go: How to get here?
Ferihegy: At tourist information you can get 24 and 72 hours Budapest card. You can buy tickets two penny-in-the-slot machine, the first is at the terminal point of the bus E200, and works with coins, and the other is at the exit of the A2 terminal and you can use it with bank note, coins or creditcard and you can buy there ticket, 24 and 72 hour ticket and family ticket.
I give you the list of the ticket-offices where you can buy anything: http://www.bkv.hu/jegyinfo/nyitvatartas.html. Ker. is a shorty for district, tér means square, híd is bridge, Hév-végállomás is the last station of the HÉV, metrobejárat is entrance of the subway/metro, kisföldalatti is a little subway so you should search for those ticket offices underground. http://www.bkv.hu/busz/200e.pdf here you can see the E200 bus stations (If you didnt know yet, this is the only bus by BKV which can get you out of there), at Kőbánya kispest you can see a big M logo, which means there is a subway, and there you can buy everything. By the way if you are on surface you should look for a logo just like that in blue to find the station place underground, or if you see an underpass just go down and most certainly there it will be.
To feel the real feeling of the Formula one grand prix i suggest to have quarters here, at Mogyoród, cause when you are not at the race, still you can hear it, and its near. You can camp here several places, and even at the last minute there are always some nice ppl offering room, mostly with the words: "Zimmer frei". I guess it would be better to write this post in german, but im really bad at that one. And of course our little "hotel", the Ring Fogadó, its really homey and as i heard the food is great, and as i tasted the food is also great at the Pipacsárda (earlier post i think i told you in the Mogyoród section which Bus stop) if you are camping but want some good food. If you already here, plan to stay a bit longer and visit the Sisi Castle at Gödöllő, or the famous church at Fót.
So if you wanna get here right after arriving to Ferihegy, i suggest to take E200 bus till the end, called Kőbánya Kispest. There you can buy any ticket you want at the subway station (good thing about staying at Mogyoród that the traveling are cheaper, you dont have to use ~300Ft tickets, for an adult person a bus cost 125Ft till HÉV, and one stop with Hév is well less then 135ft and there you are with a few walking, but i think you can walk by my earlier posted map all along, or just using the bus till other way till Mázsa tér) so you can buy your family/24hours...etc. tickets then use the subway till Deák Ferenc tér (if you really dont understand the hungarian words, in the train there are some billboards telling the stops) just make sure you are headed to Örs Vezér Tere, and not the Déli pályaudvar. At the Örs vezér tér use the underpass and straight ahead and there it is the Hév. Choose the one with the name Gödöllő, the big thingie not far from the train where lots of ppl are in lines, most of the time is the ticket buying place. You can buy the outland ticket there, but if you already have the orange ticket, or any other Budapest ticket and dont wanna wait just get on the train its totally legal to buy from the controller when he/she comes. Then just make sure to get off the train at the good station, maybe even ask someone if you lost counting them.
If you are coming by car well just check google maps, needless to say and if you use the highway dont forget to buy Vignette http://www.motorway.hu/ is your site.
If you use train to get here just use alway subway till deák tér and change if you not coming from Déli pályaudvar and the same as the airport way
If you use other options, use my first post and find out the perfect way to get here and back every day :)
Well to finish a give you a link: http://www.hungaroinfo.com/formel1/index_en.htm here are some good information (its a shame that they are talking about it as it just a bit far from Budapest when actually is nowhere near to that, but almost in heart of Mogyoród, and they dont even mention the hotels (oh i almost forgat the hotel next to Ring fogadó called Kék Laguna or something like that) or anything) but they have some good info for you.
Hope i helped. And special thanks to Tanya who made me realized that this would be an interesting topic to write about. :)
