Free start times of a tour per day. Tours can be booked far ahead (usually up to a year; the result says until when in bookable_until). Each call covers at most 31 days from date_from (default 14); date_from can be any date up to bookable_until, so call again for later periods. Times are local Leiden time. When nothing is free in the range, next_available_date tells the first day with a free time.
Tour id (the "tour" value from list_tours, e.g. "cosy-tour").
Number of guests in the group (adults and children together).
Last day, YYYY-MM-DD (inclusive).
First day, YYYY-MM-DD, any date up to bookable_until. Default: today.
