Yes, it's better than what they had before, which was nothing. Usually I can collect Amtrak Guest Rewards points AND Enterprise points for the same rental, so the Enterprise points are just gravy for me. I've redeemed once...I don't remember the rate but it was during the summer and it saved me about $75 out of pocket.

I usually get reimbursed from my employer, so I'm saving the points for the occasional leisure rental that I need. I'm "Gold" with Enterprise so my points add up slightly faster, but it's still a rather slow build-up process. But I usually rent economy cars for just a day or two at a time.
