We just returned from Tierra. We had private excursions for 3 out of 4. That may be because we were travelling with a 6 and 10 year old. On the other excursion we had another couple and it was nice to share the experience with others.
We enjoyed the overall experience. The hotel itself is quite “natural” but suits the environs.
We were happy with the food, especially the Chilean BBQ.
Ours seemed to be the only children there at the time.
As per another poster, in some ways I preferred it to Patagonia.
Happy to answer any questions.
