I have couple of large throws in a basket for use if someone wants to get cozy in a chair instead of the bed. I use duvets on the bed instead of blankets for easier removal and to switch up the decor. I launder all of them after each stay. Right now I have a padded mattress protector on the bed, but I'm considering switching to waterproof style for extra protection against bugs and spills.
Yes, it can be a lot. I think I have enough linens now that I don't feel rushed and can refresh after each visit for three or four visits before I HAVE to do a wash. I've looked into using a linen service but haven't pulled the trigger on that yet.
Cheers!
