Hey there, I'm also fairly new to skydiving as well and did AFF through Mile-Hi. They have great instructors but that place can be crazy and packed on the weekends. If you have the opportunity to go on week days I recommend it, otherwise don't be overwhelmed with all the skydivers, just meet some new people. There is also an indoor skydiving tunnel down south in Lone Tree, CO. It is a great place to train and work on stability and increase our learning curve. Also, lots of great instructors to work with there.
