CIBUS to FORGET !!! I was unable to enter with my medium-small dog after taking the tickets online I introduce myself at the entrance they register me and then I am told that with the dog you cannot enter !!! To my question why 2 years ago I was able to enter and NO this year? the answer was: this year no! Yet there was no dog ban sign! why did they switch me to the metal detector? Were they not informed? What an organization !!! What figures! and I also paid 15 for parking because of your lack of information. What a disappointment !
