We really enjoyed our stay in the dome. The location and scenery are fantastic with plenty of nearby walks...the place definitely gets cold as the evening goes on but we came prepared having read previous reviews and Don had extra blankets, 2 heaters and a hot water which were all used!
The only negative feedback is that there is no light in the toilet, so we had to use the light on our phones to use once it got dark and the shower wouldn't heat up so we couldn't use...I'm sure this is just a fixable problem as there was hot water in both taps in the kitchenette and toilet.
I would say its definitely overpriced for one night glamping, however we really enjoyed the evening and it was very relaxing and peaceful.
