You’re going to be in Denver for 2+ months potentially. You should bring your vehicle unless you have a really, really good reason not to. I drove 15 hours. Several classmates drove much further. Worth it.

Otherwise, there will be a ton of people in your class who brought a vehicle and will be happy to lend a ride. You will regret not having your vehicle the first day you are there. The plus side to that is you’ll get to make some new friends by constantly asking for rides to/from the training center, to the grocery store, etc.

It should be noted that the hotels DO have an airport shuttle, so that isn’t an issue.
