This link will provide shuttle service from DIA to Fort Collins (adjacent city to Loveland). The Limos will provide Door-to-Door service to many different locations, Shuttles, maybe not.
I have not experience with any their services, but this information may help.
Good Luck, and see you in Loveland.
