What it shows

  • Model availability day-by-day rather than checking start and end date ranges.
  • Temporary holds reserve inventory using an expiration timestamp.
  • Seasonal rate overrides link directly to calendar date records.

The takeaway

Deconstruct date ranges into discrete daily inventory records to make double-booking impossible.
