This was one of the most enjoyable things I have experienced in Vegas! My mom loved it too and we didn't experience any motion sickness at all. It was a very smooth ride from start to finish and the view was incredible.
We took our ride after dark and were in awe of the strip all lit up. The tour did a giant loop from the Stratosphere to the south end of the strip and back. It was over too fast! We would love to go again.
