All my reviews are pretty positive unfortunately I will give a negative review today.
September 28th I went to Walibi Holland with a large group, a few days before I ordered tickets online on the day there were a few sick so I had 4 tickets too much.
It was said at the checkout that I could probably get my money back, but unfortunately I just missed it. The 4 tickets are unused.
Waiting for over an hour at each roller coaster is so busy.
For us it was a drama !!!!
