The views are incredible. How often can you say you saw the sun set and the stars come out at 13,000 feet? BUT that's where the enjoyment ended for us. If the views alone are worth the money, then more power to you! However, if you are interested in an actual TOUR, then I'd go somewhere else. Our guide, Stefan, was nice but was not an effective tour guide and more like your neighborhood Uber driver hired off the street. He perseverated on irrelevant info (e.g. when we could eat our sandwich, his personal background), often repeated himself, and gave some misinformation (FYI, the moon is not a planet). We had different expectations for this tour, like some more in depth info of the astronomy and geology themes to serve our fascination, and what we experienced was far removed. If you're under the age of 26 and looking to get some good pictures to share, this is the tour for you. If you are looking for any sort of substance to go with those photos, go somewhere else. Additional tip: if you don't like veggie burgers, bring your own food.
