Was Promised a Free Night to Compensate for Bad Experience, Never Got It
I stayed with my 3 boys and when we checked in I was told I was lucky enough to have been upgraded to a king room. I didn't want a king room, I was travelling with my 3 boys and wanted 2 queens. Don't make it sound like you're doing me a favour of upgrading me when the problem is that you've overbooked your rooms. I was told not to worry, that there was plenty of room for all of us in the king room, that all the queens were sold out. I hesitated, but it was getting late and they told me they'd put a cot up there as well. 
Well, this would turn out to be the worst hotel stay and vacation I've ever had with my kids. They came up with the cot, which blocked access to the rest of the room. If we wanted to go to the washroom (which was very lovely, but takes up half the room) we had to jump over the cot to get to it. They children did not sleep well since I could not separate them and the rest of our Seattle trip was ruined on account of their tired behaviour. Before you judge and think that the room was not to blame, keep in mind that these kids have slept in many hotel rooms (in separate beds) and been fine. 
We proceeded to the Space Needle (where the kids were so tired they melted down and we left Seattle early) after I'd very nicely told the staff at the front desk that our upgrade wasn't really the best thing for us. That was met with a smile and an apology. The staff were nice, but they are young and don't deal with children very well. 
I wrote an email and shortly received a phone call afterward, apologizing for our hotel room experience. I was advised that I would have my next night taken care of so that we could enjoy our trip in the room we had intended. I never received anything after the phone call. I called back 2 months later inquiring and was told somebody would return my phone call, but nobody did.
I will say that had I been travelling with my husband alone or had we gotten the room we wanted, we probably would have really enjoyed our stay. Hotel was clean, rooms were nice, bathroom was exquisite (though it does take up a lot of room space).
