Hi there
I just looked at your listing and could suggest a few things.
Firstly, I couldn't book just a single night.
Secondly, it's the same price regardless of how many people is staying.
This means for the 10-12th Nov, 1 lonely person would pay £893.81 for the 2 nights and 14 people would also pay £893.81 for the 2 nights.
Sorry I don't know the conversion rate but it works out to be very expensive. Maybe have a minimum base price for 6 people and increase the price per person up to 14 to cover the extra people.
Listing looks great tho, and reviews are all good as well!
Good luck!
