The biggest problem is finding your way inside the fair and navigating between buildings. It's huge and there are no signs, especially if you didn't enter through the main gate. Interliber was, as usual, wella organized but pretty crowded in sense that aisles should be wider for such large masses of people coming from all round the country. Inevitably that would make the whole fair larger and spread out to more buildings, I'm aware, but, honestly that, and lack of toilets (they exist, but not too many of them) are my main things to point out
