While we have never requested extra soap bars, shampoo or laundry detergent (as we bring our own) they have always been great at re-supplying toilet paper, trash bags, dish soap, dishwasher soap, and paper towels upon request.
The full kitchen is well-stocked. Generally you will find: blender, coffee maker, dish towels and hot pads, placemats, silverware, various cups plates & bowls, pots & pans, cutting board & knives, large salad bowl, Pyrex baking dish and/or casserole dish, baking sheet or tray, 3 Tupperware containers with lids, plastic pitcher, various kitchen utensils.
We have stayed in enough Marriotts we are aware of kitchen items which should be included and they are pretty standard. In a few timeshares we have even seen a kitchen inventory list attached to the inside of a kitchen cabinet.
