We’ll be there for 4 days, with dd 13, we want to do a mix of historic and fun, so eg. castles, but maybe an immersive art experience or the selfie museum too. I’m also wondering if the Budapest card is worth it, which sites are best for booking an evening river cruise (Get your guide pops up everywhere, but is it the best one?). Also, has anyone been there on the national holiday of 23 October before, and what’s open on that day?
