One of the nicest things in life is to lie in a seaside tree cabin, looking at the sea and dreaming that one day you will sail to Saaremaa over the blue sea. This is exactly the cabin that Lotte and Bruno invented for themselves. If any visitors of Lotteland would like to lie in their cabin, look at the sea and dream, then they are welcome. It will make Lotte and Bruno happy. Dreaming adds excitement to life.
