I've been to Moon a few times and my experiences been good and okay but never bad. I absolutely love the view! The line can seem long because the only way to get to Moon is via elevator so obviously everyone has to wait for the loading and unloading process. Moon is not that big so walking through the crowds can get annoying but no different than most clubs. The retractable roof is pretty cool...offers a nice view of the moon and some ventilation. The music is fun!
