Flight
While there are some smaller airports here within Northern Colorado, Denver International is the most likely one that you would need to fly into. From DIA to Estes Park, it is about an hour and a half to two hour drive depending on whether you take toll roads (which are optional) or not :)
Hotel
This is a good cheaper option that is near to the main hub of Estes attractions! Also it is very close to the venue :)
Travel Note
For those who would like to spend their stay in more of a cabin/mountainous setting, try these! Misty Mountain Lodge Discovery Lodge Coyote Mountain Lodge
Hotel
Here is a close hotel for those not wanting to stay in Estes. This hotel is in Loveland and is about 18 miles from the venue (about 45 mins).
