Believe me, up until last year when I saw the discussion here on DIS,
gullible me thought that all hotel/resorts changed the sheets/blankets/bedspreads between guests. I was horrified to find out that it wasn't true. Since then, I have been bringing my sheets on our vacations. Believe me, it takes up a lot of room in the luggage. But, I can't bring myself to sleep on something that someone had already slept in.

I just find that disgusting.
On my post #31, I, also, mentioned that I would love the perk that guarantees that bedding would be changed between guests.
But, until then, I'll be bringing my own bed linen.
