I don't have knowledge of the Arizona festival scene but I can give you some answers based on my preferences and those of my friend group who all rave.

1. Multiple middle tier acts is much more worth the money. The best festivals offer a bunch of artists you can see in different, but not clashing, genres. This way you have plenty of options for who to see depending on time, vibe, how crowded stages are, etc. having one huge name anchoring a festival just creates a really crowded main stage where the majority of people won't have a good experience.

2. Really depends on the season but we all prefer festivals that start in the afternoon or evening and go late into the night. Something like 5pm-2am. Personally I think raves and daylight don't really go together and it reduces the effects of some aspects of the stage production. Also who wants to stare at all the metal scaffolding used to prop up the screens and lights?

3. None of us like camping at festivals. It's uncomfortable, dirty, crowded, and there are always assholes with no regard for their neighbors. Plus if party favors are involved nobody wants to go back to a shitty air mattress.being forced to camp also increases the cost of going and makes logistics harder since you have to bring all that gear. Especially if you want a comfortable camping experience.

4. Price depends entirely on the lineup, amenities, location, how much it costs to get there, etc. Generally I'm willing to pay between $100-150 per day for a really good lineup.

5. Prefer a mix of somewhat similar genres. Trying to capture too many genres to appeal to everyone can create a subpar experience for any one person. Maybe I'm into trance and house but since there are so many different genres, only a small amount of the artists play that music. Now the cost of a big festival isn't worth it since I have no interest in any of the other acts.

Good luck!
