Just back from a few days in a holiday chalet (UK). It's on a site where the chalets are privately owned and let out through a management company. We've been going for years (different chalets) and this is the first time I can remember there being plastic sheets on the beds (under the sheet but on top of a memory foam topper). I woke up several times the first night feeling hot and sweaty. The next day I took the sheet off, to see Do Not Remove written in felt pen on the plastic! So I slept on a beach towel after that - better, but it rucked up. I want opinions on whether you think this is reasonable. I want to go back to that chalet but not to sleep on plastic. I can't imagine how unpleasant it would be sleeping on that in the summer. TIA
