Il 21 April still seems far away, ma, take heed, are little more than 60 days, therefore it is time to look around to organize the visit to PPM2023 in Brno.
The right compromise between prices and availability is around two months, before it is useless, there are no discounts, but waiting too long risks having to settle for what's left. My personal travel agency knows it well, and so he always finds a way to surprise me (pleasant, ça va sans dire) discovering characteristic and suggestive places.
Know that getting to Brno is quite easy. Vienna is only an hour and a half away, with the availability of well 15 trains and 12 autobus, and the Austrian capital is widely connected with the rest of the world.
If you still have doubts about the opportunity to travel to the “distant” Brno, I report below the presentation of this edition of the exhibition. See if it's still not enough.
