My husband and I visited FlyOver Las Vegas and really enjoyed the rides!
We were excited to experience both rides because we travel to the west coast often and had just returned from a trip to Iceland. We would have bought the double ticket but FlyOver requires you to buy times that are pretty far apart and would have required us to devote an hour and a half to being there, which we didn't have time for on the first day. We ended up buying tickets to the Wild West show first.
The Wild West show was a lot of fun. We got to see many of our favorite places (Golden Gate bridge, west coast, Monument Valley, Colorado) and some new places as well. The movement of the ride and the wind and other effects truly make you feel like you're flying. It was similar to Soar in Walt Disney World but even a little better! As someone who gets motion sickness sometimes, I was a bit worried, but I didn't have any issues (and you can easily look upward at the top of the ride to get your bearings).
We returned two days later to do the Iceland ride because we had just come back from Iceland and skipped Flyover Iceland in hopes of doing it in Vegas. This show was very beautiful as well and showed us a lot of places we saw while visiting Iceland's southern coast, Snaefellsnes Peninsula, Golden Circle, and Reykjavik, and plenty we didn't see that was more north than we had traveled. It captured a lot of Iceland without a lot of the inconvenience and discomfort we had dealt with actually being there (it was cold, windy, and rainy much of our trip).
The price was what I would expect for this kind of attraction in Vegas and we would definitely return in the future if they add different rides! I just hope they tighten up the schedule so people who want to ride both don't need to spend so much time (or come back on different days).
