Platinum elite, upgrade received before arrival.

At check-in, the agent said the hotel policy is no guests who live within 50 miles of the property. Apparently this is how many hotels in the region try to keep drug dealers/users out.

Both the hotel and IHG customer service agree that the hotel did not disclose the 50 mile radius rule in advance; not mentioned anywhere in booking process or on website.

Impossible to talk to anyone at IHG customer service who could provide any resolution or advice. Hotel's only advice was to find another hotel without the rule.

What is reasonable compensation for a situation like this, and what is the best way to contact IHG to get said compensation?
