Just checked in to this hotel, had reserved a double room and they gave us two singles. Went back to reception and asked to switch. The woman there informed me that rooms with double beds were for families and that we are not a family. I couldn't believe what I heard so I asked her to repeat and she said that no, we are not a family and there would be no double bed for us. I was speechless for a minute, then asked her if I showed her our marriage certificate that would suffice. She said no, it's for families with children.

We are still here, in a room with two tiny twin beds, as there is nothing else decent available nearby or I would have walked immediately. I really don't think I'm making a big deal out of nothing, and it wasn't a communication problem as we were both speaking Spanish. I already contacted IHG chat and they gave me the phone number and email for the front desk (gee thanks guys).

So, questions: how should I escalate this, and to whom?
