"The classic 4 plus lodge was comfortable and roomy for our family of four. Staff at the resort were very friendly and everyone spoke impeccable English. Lots of food options (including all-you-can-eat buffet).
The bed linen and towels need to be hired when you arrive and check in. You could take the towels to the Aquadome; however be aware they are the smaller, thin white towels.
At the Aquadome, be aware that signs tell you to strip naked and shower before entering the pool area - be prepared to see nudity, it's very normal in Scandinavian cultures (genders have different changing areas). The Aquadome was excellent - you can even load up your bracelet tag with money to buy food within the swimming area.
If we were to go again, we'd probably buy a gold tier entrance to include the bowling, golf, shuffleboard, darts etc as we paid out a lot for these while there.
Adventure Tower and zip line also worth a go.
Lego House was a short drive away, and Legoland was walkable. The sushi restaurant opposite Lego House has all-you-can-eat sushi ordered by iPad and delivered by robots. Not much else to do in Billund.
Overall an excellent stay."
