I'm not sure what you mean by amenities. The studios do not have a full kitchen but they do have a kitchenette with microwave, refrigerator, toaster, coffeemaker and wet bar. There is no jacuzzi. Almost all of them have a deck or patio. The studios do not have "real" dishes. They have a start-up of paper goods, some real glasses and some real coffee mugs (you can request more as needed). You can also request a can opener or bottle/wine opener if necessary. There is no VCR nor DVC in WDW studios.
When at OKW in a studio, we go to Turtle Shack pool and have a nice frozen libation or two while doing the laundry - relaxing way to get the chores done!
