This answer has been flagged as not being an answer to the question, and it isn't. But as always on this site, it's a record of first-hand experience that's tangentially related to the question and very much likely to be of interest to anyone reading the question and answers in the first place. Feels like a shame to delete it, perhaps making it a community wiki as a way to distinguish it from the others? I know that's not the original intent of wiki answers but as I said, deleting it feels like a loss.
