My wife and I wanted an overview of Dusseldorf to get us started on a five day visit and this was perfect for us. Our tour guide (Ricky) was personable and knowledgeable. Our group was 6-8 people across a broad age group and he kept everyone engaged. We referred back to our tour many times over the next few days as we explored the city in more depth, following up several times on suggestions and recommendations from our tour guide. Definitely worth the time and money!
