How do I get from Billund Airport to Legoland?

So, here's my situation. My family and I are flying into Billund Airport. How can I get to Legoland quickly? Our flight arrives at 5:30 p.m., and I'm afraid we'll hit rush hour. You know, I don't really want to sit in traffic. I read about different options for quick transportation from the airport on the GetTransfer website https://blog.gettransfer.com/billund-airport-to-legoland-quick-transit-guide-transport-options-travel-time-3/ . I'm interested in a shuttle service. Could someone please tell me if they've used this type of transport to Legoland? I'm very worried because it's our first time there and I don't know the area. Will I be able to quickly find my way around and understand where to go?
