@Heidi703 Wow, your listings look amazing.
I can imagine that such an atmospheric location inspires guests to do some wacky things with candles, so in general I don't recommend providing them (except for the no-mess LED type). Of course, that's no defense against guests who bring their own equipment to play kinky Phantom Of The Opera-themed games in bed.
On-site hosts eventually become experts in obscure stain removal techniques, and wax is actually one of the easier ones, but it's probably cheaper to buy a new sheet than to pay overtime to a beleaguered housekeeper. In that sense, all the extra damage and wastage is the trade-off for outsourcing.
And if you're not 100% sure which guest caused damage, any claim is DOA.
