My partner is moving to Boulder for work early April. He will need to rent a car for the first month to give him time to find one to purchase. Does anyone have any recommendations for (hopefully) inexpensive car rental in Boulder. He doesn't sleep on planes, so will have been awake for 24+ hours when he arrives in Denver, so we thought he should get the shuttle to Boulder, rather than renting from the airport and risk driving on the opposite side of the road, fatigued and not knowing where he is going! So any information for good car rentals in Boulder would be appreciated. We've checked online but its only the major companies that show - but this could be the range available. Many thanks for any information.
