Red Rocks Amphitheater Adventures

Will be going to Colorado this coming weekend and we’re going to be seeing the DJ Alison Wonderland at red rocks for both her main set and a surprise after party so I’m wondering if anybody has any suggestions about basically anything for that night. Is Uber the best option how early should be getting there for show starts at 10 how crowded is it going to be etc. etc. any information you can give me would be greatly appreciated I promise to post pictures and I return
