wales football games away

hi does anybody know where the games in Croatia and Hungary are going to be played as wanting to start booking hotels and flights.
cheers

Croatia normally play in zargreb but i think also play games in another city from time to time, Hungary always play in Budapest and are currently building a new national stadium but not sure if this will be open in time for Wales game. We got flights to Budapest from Heathrow £86 return a few days ago and there wasn't many seats left on the flights we looked at. Zargreb and budapest are only 200 miles apart so i wouldn't be surprised if theres organised trips flying into zargreb and out of Budapest
We are looking to do Slovakia in september as well
