There are no nightly rental fees when you book a trip. Accepted members only cover the cost of cleaning and a small service fee per stay. This service fee varies by length of stay, but is typically $5-35 per night.
Members also have the option of purchasing a Kindred Passport for $600, which unlocks $0 service fees for an unlimited number of trips booked that year.
The Passport typically makes sense for members who plan to book more than two trips in a year, which is fairly typical usage. You can pay up front or in monthly installments.
