IHG has a separate paid InterContinental Ambassador recognition program for stays at InterContinental hotels where most (if not all) IHG Rewards Club Gold and Platinum benefits don’t apply.
You get guaranteed room upgrades, guaranteed 4PM check out, a free weekend night voucher and a fruit welcome amenity.
Now, IHG has made small change to the benefits listed in the program terms and conditions (access here).
You are no longer guaranteed replenishment of mineral water on subsequent days of your stay. This was previously benefit of the Ambassador status.
This is not a huge change, but may end up costing some folks another $20 per night if they just take the mineral water out from the minibar and they are not Royal Ambassador members (complimentary minibar beverages).
Providing a couple of bottles of mineral water per day cannot be THAT expensive considering the rates that most of the InterContinental hotels charge.
