Definitely worth a visit. As an English only speaker, there were many signs in English and German. Every member of staff I spoke to had a very good grasp of English. I was in the Tropical Rain Forest area when a member of staff called me down to see the feeding of the stingrays. Lots to see, crocodiles, sting rays, octopus, nemo and friends. There was a small 'cinema' but it was in German so didn't see that. I visited on a Monday afternoon, no queuing at all. I have an annual pass which is great value but cant comment on individual prices i know you can get a lot of 2 for 1 offers. Small cafe at the end with nice outdoor seating area and has a small gift shop. Really good fun and I appreciate what they are doing to preserve and protect.
