It is great to have such a pass, as you get some advantage to other visitors. We had only two days to visit, so it is a little short, you need at least 3 days to cover all exhibitions. For senior persons, the cost does not really worth it, as all exhibitions are about 20 discounted for senior, this not being reflected in the pricet we paid to Viator.
Good deal with good value easy and efficient organization for a good price.
Lots of fun things to do. Although we didn't get around to doing everything!
