Review for Casino Admiral Prater Review For Casino Admiral Prater Google User Jun 23 '18 at 10:12 Quite possibly the best theme park I have ever been to. My wife and I thoroughly enjoyed regressing to 10 year olds to jump on as many rides as possible and then retreated to one of the many lovely bars to catch our breath. Would recommend the park to families and couples who want to make the most of their trip to Vienna. The park is free to enter and you pay per ride but we found the prices reasonable and well worth it. View full site to comment or like
