I'm not quite sure what you guys planning with "Romkert" as an accommodation, as far as I know it is an open-air nightclub. Are you sure about that?
Or are you looking for it at the lake Balaton? Anyways to anyone who search for this kind of answer, check out this site: http://welovebalaton.hu/en
here you can find accommodations, restaurants, event programs, reviews and useful informations - not only for the young ones. about 5 years ago
