In my profile I have listed 1) extra feather pillows, 2) extra towels, 3) refrigerator.
Most of the time they are all in the room at check-in. The exception is if my flight has an early arrival and I am at the hotel before noon, and then these things always seem to follow shortly after check-in.
Sorry to hijack the thread.
I too have the refrigerator in my profile and its hit or miss whether I get it or not. BUT, I've screwed myself several times lately as many FS have replaced minibars with little refrigerators and I've never opened the door to notice until it was too late (like when leaving). I'm just used to ignoring the minibar completely.
