Flight
Denver International Airport is only 50 minutes from the venue, and is the best place to fly into for out of state travelers. I would consider getting a rental car so you are able to enjoy all of what Colorado has to offer.
House Or Rental
I would recommend either staying in an Air BnB, or Hotel in Boulder or Longmont. Longmont is closer to the venue, and Boulder is right next door with very fun shops and a lot of Hiking!
House Or Rental
There is a two night minimum here. So cute and gives a nice Colorado experience!
