@Chateau0 Elan Executive Estate 10 people booking a vacation rental IS an event 🙂 Whether it turns out to be a wild party will depend on how adept you are at vetting guests pre-booking confirmation. For instance, you might not want to accept a booking for ten 19 year-olds on spring break, but Mom, Dad, Aunt and Uncle, Grandma and Grandpa and a couple of their friends would be a safer bet. And like other have said, if they can afford your place, they can probably afford a private chef.
I have a friend who is a massage therapist- she gets called into private rental homes to work on people all the time- she is not considered an unautorized person who's not allowed in without the host's permission.
I would think of researching chefs and caterers in your area, checking them out as to professionalism, reviews, and insurance and having that info available for guests in a house manual, just as hosts recommend local eateries, sights and cool places to visit.
Most of the high end listings in my town have house manuals with pages of local business cards and flyers in them- anything from restaurants to caterers to massage therapists to dog walkers to car rentals, etc, etc. The more you can provide to make your guests feel like they were provided for well (I'm not talking about asking for you to install AC in every room, 800 count sheets, "I know you don't accept pets, but please can I bring my 3 Bull Mastiffs, they're totally well-behaved", or other unreasonable, entitled demands) , the better.
