There are club tiers. Jewel falls in the middle for Vegas but it does stand out. It helps that it's in the Aria. Put Jewel inside of an older MGM property and I'm not sure if it would do as well.
My Night
Guest listed and got in fairly quickly. There was a performer that night and so the club ended filling up but slightly before 12 beat the lines. The club's layout reminded me of Light (Mandalay Bay) but on the more modern and upscale side. Their bottle service was flashy but classy, which isn't always seen.
Security and bartenders were cool people, no issues. Restrooms were nice, standing areas on both the bottom and top floors are congested but with the ability to find room, if you try hard enough. The best part was knowing the club isn't on the 20th something floor and being forced to stair it down half a hotel to leave.
Jewel is not an Omnia or XS, it's just a small well designed club that is definitely not the worst outcome. If you've learned to not put all your bottles in one basket, make Jewel your first stop of the night, it doesn't hurt the morning recap.
