Was pretty excited to visit the LINQ, but when I got there.. there wasn't much to look at. There were a couple of restaurants, and some apparel stores. If you enter LINQ hotel, follow the signs to the promenade. It's pretty interesting how you would have to pass a bar/restaurant before you reach outside. Don't mind people playing beer pong because you will walk right pass them. As you walk outside, there is a bar that is connected to LINQ, so you will see a few high tables outside for the patio.
Once you are outside, the Highroller is towards the end of the Promenade. A lot of people walks towards the end just to take a photo of how BIG the Highroller is and close. There's not much to explore other than the Highroller. A lot of people seems to go to the LinQ promenade for the photo of the Highroller, other than that, I do not see why that many people would stick around.
