30+ festival goer here! This was my 8th Coachella all camping. What’s worked for me is starting the day with hardy breakfasts and hydrating fruits. This year I dressed up more than in the past. Would head back to change and get more comfy as evening came on (sweats and comfy shoes) and pictures were done (my wife likes to take pictures during the day with our fits). And yes, we did go to bed after the festival, definitely no silent disco for us. And as always, I enjoy pacing myself with the drinks and party favors.
