I'm planning a visit to the Wadden Sea National Parks and want to know what visitor centers are available and what kind of facilities or exhibitions they offer. Please navigate to the 'Besuchen' section, then find information about the visitor centers. List at least two visitor centers and describe a key feature or offering of each.
Navigate to 'https://www.nationalpark-wattenmeer.de/'. Click on the 'Besuchen' (Visit) link. Locate and click on the link or section related to 'Besucherzentren' (Visitor Centers) or similar. Identify at least two distinct visitor centers. For each identified visitor center, extract a key feature, exhibition, or offering. Synthesize the names of the visitor centers and their key features.
The agent successfully navigates to the 'Besuchen' section. The agent successfully navigates to the visitor centers information page. The agent identifies at least two visitor centers (e.g., Nationalpark-Haus Carolinensiel, Nationalpark-Zentrum Multimar Wattforum). The agent provides a key feature or offering for each identified visitor center (e.g., for Nationalpark-Haus Carolinensiel: 'Ausstellungen zu den Themen Watt, Salzwiesen und Zugvögel' (exhibitions on mudflats, salt marshes, and migratory birds); for Nationalpark-Zentrum Multimar Wattforum: 'größtes Aquarium für die Nordsee' (largest aquarium for the North Sea)).
