+1 Dollar Tree and IKEA both. Add Marshall’s/TJMaxx/HomeGoods for inexpensive serving dishes and table linens.
The Airbnb host might (should?) be able to send you pics of what is available for cooking/baking/serving (or at least of what’s in the cabinets) - especially given the holiday period rental.
If you make a list of what tools and serving dishes you need for your menu, cross the two and supplement only a few things (except critical tools - carry those!). Ask if there is a cutting board that will fit the turkey.
Williams Sonoma / Pier 1 have pretty melamine platters that would work for the turkey and are lightweight. You could ship those as well as any small, sharp items you can’t fly with directly to your mil’s senior center (Amazon has any number of cheap knives, corkscrews, and peelers). Or ship what you already own in a USPS fixed-rate box or padded envelope - $7/13 for medium/ large I think, which fit quite a lot. Label and bring a second one to ship the same sharp things back to yourself.
Paper doilies or cloth napkins can “prettify” a bowl for rolls or a plate under pies.
Remember to pick up plastic containers and zipper bags for leftovers at DollarTree, and maybe even heavy foil, parchment, and/or plastic wrap. They will also have festive paper napkins and tablecloths (disposable or cheap) if you want those.
While you can certainly make the simple sides, consider ordering them to free up the time (and cooking space) for more meaningful-to-you things like your rolls. Everything takes longer in someone else’s kitchen too, pare late down the list and freehp some time for yourself.
It’s lovely that you are flexible and willing to bring the holiday with you - that’s the real celebration here, family and togetherness, whether or not it looks or tastes just so.
