Earnings from third party hotel guest bookings are shared among owners based on their individual usage patterns, specifically, their unused days during both peak and non-peak times. The more unutilized days an owner has, the greater the potential for earning. This sharing mechanism applies when multiple owners are involved, with the distribution of earnings reflecting the proportion of unutilized days each owner has during the time the residence was booked. So, it's all about finding the right balance - the less frequently you use your property, the more opportunities for earnings you create.
