Conceivably, you could shuttle from MB to the Courtyard; then hoof it a few blocks north to the In-N-Out; then gorge vociferously; then waddle back to the Courtyard; then take the shuttle back to MB.
I'm the adventurous sort so I'd be fine with hoofing it across Tropicana. You don't actually walk on the freeway you're walking on Tropicana. Speed limit is 45 on that road. If you actually look before crossing the exit ramps, you'll probably make it.
The sidewalk runs along the south side of Tropicana.
Walking from the Marriot to InN Out is much more dangerous than walking from NYNY/Excalibur given the number of drug dealers/pimps you're likely to encounter.
A lot of them live in the American Motel just South of Tropicana on Dean Martin.
