How Fill the Calendar works

You run one 1-bed apartment for four weeks in the market you pick. The typical nightly rate comes from real 2026 data for that month. Twenty-two guests send booking requests one at a time: check-in, number of nights and the price they offer. You have up to a minute to accept or skip each one, and stays can't overlap.

Some requests are traps: a cheap early stay over event nights, a one-night stay that splits a week a longer guest wanted, a low offer on a weekend that would have sold for more. Partway through, a slowdown hits and offers get fewer and cheaper. At the end we compare your month with the best possible month from the same requests.

Typical rates come from RevOpt's 2026 market data. Guests and their offers are simulated.
