Staying tonight at the HIX South on Bayshore in Burlingame. Should have known the $70 rate would have some strings attached. When you search for hotels in this area, where all the IHG properties display, this property shows:

• Free Breakfast
• Pool
• Wireless Internet
• Business Center
• Airport Shuttle

When you look at the individual property page:

• Complimentary Airport Shuttle Service Available For :San Francisco Intl Airport

SHUTTLE
Shuttle information is not available

This means there is no shuttle. If you're planning a stay here in the future, best to check ahead and see if they're operating a shuttle., so you're not surprised like I was.
