I travel by train lots with my family. I hate to fly, too! It's not necessarily cheaper if you get a sleep compartment, but it is still relaxing and fun. The trains are a bit worn, especially that line. Not horrible, but don't expect Canadian or European quality. Anyway, I would only have one warning for you: the one time we planned a trip to Disney on Amtrak was when we lived in Houston. So it was the same Amtrak line you will take. In fact, we were going to pick it up in NOLA to save on some time (lots of stops in TX). We never did make the train, because they called just as we were leaving to drive to NOLA to tell us that the train was 14 hours behind schedule. Now I can be flexible, but that was missing an entire day of vacation! Also, it was going to put us in on a different night than our reservation. So we just decided to drive the whole way and they refunded our money. I have found out since that this particular line gets that far behind schedule often. So just be sure that you either have a back up plan (driving), or the flexibility in your plans to shift a day of vacation. Congratulations on the impending nuptials!
