Bellagio has always worked out great for me with valet attendants. Just state you want to park it yourself and a valet attendent will ride with you to a safe under roof main floor spot away from any potential harm or tampering. Car is always being observed by their security while in this secure spot. Remember to tip well. When you go to get your car, its close enough for you to go and get it yourself and most likely an attentendant will be there to guide you out just so they can hear and be next to it. Have a great time.
