Microsoft's code (100857558) provides competitive 8-15% discounts but sometimes requires ID verification. In major business markets, this risk is typically minimal.

Corporate codes work across all IHG brands including Holiday Inn, Holiday Inn Express, Crowne Plaza, and InterContinental.

Always book directly through IHG's website to ensure you receive loyalty benefits and can modify or cancel reservations according to IHG's policies.

The AAA code provides the safest universal option at 5-10% off standard rates, requiring only your AAA membership card for verification. While the discount is smaller, it eliminates any verification concerns and works consistently across all properties.
