This experience was so intense it actually changed my way of thought. After we went out of TRAP, I kept looking for clues all around me, noticing every little detail of my surrounding. Needless to say, it was interesting, to say the least. the trap itself was challenging. Very challenging. We were 4 puzzle-loving-geeky-people, and still we needed quite a lot of hints to solve some of the puzzles.
Still, it was an hour well spent. Personally I thought it might have been better if it were a bit longer than an hour, but my friends disagree with me, so it's probably just me.
Anyway, if you have an hour to spare in Budapest, this should be your first option. Actually, even if you don't, you should clear an hour of you schedule to do this, it will be worth it.
