Flight
"The easiest (and cheapest) airport to fly into is Denver International Airport (DIA.) You will have to coordinate carpools/rental cars to get to Wyoming from here. You can also check out flight options to Laramie Regional Airport (LAR) or Cheyenne Regional Airport (CYS)." - Jarvis and Niki 2019
Hotel
We recommend staying in Wheatland (or Laramie/Cheyenne if you are looking for a bigger town). Looks like most people will be staying at the Heartland Inn or the Super 8 on Friday night. There is also camping available on the same site as the reception, so we recommend camping on Saturday night so you don't have to drive. Feel free to camp Friday as well!
