I went on LINQ website and bought tickets for general admission for 2 in advance.
So I seen on Groupon the prices and I compared to the general admission. The general admission is best value at night is beautiful. We bought our drink LINQ bar before boarding. I suggest don't go for the open bar deal because it not worth it & as a30min ride was just enough time to enjoy and I didn't even finish my drink because I was too busy taking pictures and video and embracing the scene.
I would love to go on high Roller again my next visit.
