About online poker in Hungary: so far it was a huge grey area, basiclly the goverment didn't really cared about it, no real regulations. This year they came up with a law-plan which was than approved by the parliemanet. What i read so far, is mostly about the restrictions how can someone operate online poker in Hungary, not too much about the user side. The main point, the operators has to get a licence approved by the hungarian tax station, if they have it, they can operate poker and horse betting (casino games and sportsbetting was left out from the law, so basiclly it stays grey area). (I assume all bigger sites will get this licence very fast because the hungarian market is really huge.)
I think that not too much to worry for the players to be honest, the goverment just found out its a huge tax revenue opportunity.
Budapest is really beautifull, living is very cheap compared to the Western-Europian countries, you will find trillions of activities, but to be totally honest, i think its not the most ideal for a poker player. (i mean, i dont know how serious you are, if you plan to play live events and so on...for example, if you plan to travel a lot to Europe, the airport is not the best hud with its offer, or lets say, you wont get the best deals there, Vienna is way better in this case).
