It is true that the organization tries that everyone stay in the official areas, but just to avoid problems with security. But as I said, this is not a problem because there is several areas prepared by the organization in every SS, all very different from each other, with all that you need and more.
I see no problem staying in spectator zones, if they are different, spectacular, large and with good conditions, which is definitely the case of Portugal. As a matter of fact, in relation to spectator zones, Portugal should be one of the best events in whole championship.
