Yes, GU summed up it well. I was not contemplating that much of the possible financial aspects for the governments involved rather the impact of a potential decrease of US visitors.
I don't have the breakdown of visitors by nationality to Hungary, but the country has been a strong inbound tourism country for a long time (not on the scale of Spain or France of course) I don't know if cross-border trips (dentist, shopping, whatnot) are counted, I'm not familiar with the methodology - but it's fair to suppose that there are more Austrian or German visitors than Chilean or Kenyan
