Really amazing all around.
We did the sunset tour on a Sunday. Parking is easy, workers are friendly. They have a nice lounge area while you wait, not like sterile hangar type of thing like I've experienced before.
We had Mark as our pilot (I forget his last name), super nice. Very professional but we finally got him joking a little at the end.
The tour around Vegas was great and comfortable. I haven't done a helicopter tour in ten years but these seemed a lot more comfortable than I remember from a different company (in another city). The flight was smooth even though it was really windy, I honestly didn't think they were going to let us go up.
I know some people might be sketchy about trying this if they've never been in a helicopter before but you're up in the air before you know it, there's nothing scary about it.
I'd definitely recommend this. Might as well get a lifelong memory for your money in Vegas than wasting it on slots that you never win.
