I went to Jewel several times with groups of friends. This club had DJs that we liked so we decided to go to Aria to check it out since this club i also pretty new.
This club is conveniently located inside Aria on the strip and parking will be easy so no problem at this level. The line can be a little long on the busiest days (Friday and Saturday of course), but nothing as bad as OMNIA or Hakkasan.
Fortunately, the atmosphere inside the club is nice with good EDM music and the club does not get overly packed like the two other clubs mentioned above which makes it a good option in Las Vegas if you want to escape the crowds. Do expect to spend quite a lot of money on your drinks though.
Last but not least, this club is definitely smaller than other Las Vegas clubs even though it has two levels. That shouldn't stop you from going there though because it is still a good club.
Overall, my experience with Jewel was good and I would recommend it. Feel free to message me for any additional details that you may need!
