Great place, beautifully done and the photography is exquisite.
About the only thing I would is rethink is dropping it to 6 (not 😎 persons. I see you been at it for a long time (-2020) without incident, but the world has changed somewhat since. Allowing 1-8 to pay the same absolute price would get me nervous for 2 reasons: it may be too inexpensive for so many people and when there is no progressive scale in price, the 3rd & 4th couple invited may not fit the place as well as the 1st & 2nd ones. Usually they tend to be fillings, thus 'different'. Catering / Cleaning a place accommodating 8 people, we have noticed becomes exponential tougher after 6 people.
I would make it $299 first 4 guests, $50 per person the next 2 and when only asked about the 4th bedroom, allow exceptions after having the benefits of 'interviewing' the applicants.
