The concept is good, and we were able to see the stars and the moon through the clear plastic dome of our room. Unfortunately, there was a very, very strong wind both nights of our stay. As a result, it was very noisy, making it difficult to sleep. Moreover, the wind was so strong that the "walls" kept blowing inwards. We changed rooms for the second night, but the second room was only somewhat better. Of course, the hotel management had no control over the weather.
On the other hand, the hotel management could control the food (dinner and breakfast), which we thought was o.k. but not great.
