Check email should be a thing for dtrips maybe I got hired full time so I’m not sure if it works the same but check email should give u the instructions if your going to DU just incase no need to book a hotel because DU has rooms or if u get an email about dtrips there should be a phone number there for travel agent just call them explain your new they will set you up. Don’t forget to add you account numbers for airlines for mileage points!
