Enterprise are only pretending to have a loyalty program. They screw you. Registering is not enough to get point credit for your rentals. Hidden in the T&C's that nobody reads, there is a requirement to do an activation. Why would anybody hide that stupid extra step in T&C's except to cheat you out of the points that you wanted to accrue from first rental after registration? Like duh... why would you be registering supplying that number the next day for a rental? You do not learn about the sneaky extra step until your package arrives 6 weeks later not even in the immediate confirmation email you received after online registration. We were deprived of $1,200 spending points that fell between registration and activation date. Sure makes you wonder what other risks you are taking when renting from them!
