Hello, I would like to come between the 10th and 12th of september but those days are in grey when I want to buy a daily ticket although they say the park is open all year in 2018. Can someone help me?

The park will be open all year, but those that have bought the grey season holders can go.

The park will be open, but buying advance tickets may not be available for those days yet. They should be available late July. I'd wait before buying and paying the 85 any day tickets

Park is open all year. It is only grey for season holders.
