Any Amtrak codes or coupons out there?

[EpcotMatt]

I’ll be using Amtrak from PA to Kissimmee for a trip to the World in January & was hoping to nab some codes to cut the cost a bit. I know my AAA will give me a 10% discount. But are there any other codes out there? I remember seeing some 25% and some 50% off a companion fare, but forget the codes. Unfortunately, the date of my trip down falls within a blackout period for most of the codes, but the ride back should be covered. Also, several of the codes I’ve found don’t include the specific train I’ll need to use either. Bummer. But I know if anyone knows of any codes or coupons, the DIS would be the place to check. Thanks!
