We procrastinated once, waiting for regular Amtrak rates to go down, they usually run a 35% discount few years back, and that year they had no sales. By waiting, the train was full, no seats. I saved nothing and had to drive to WDW, which I hate and used the train to elliminate. No more waiting for me, pick my resort, pick my dates and call Amtrak for tickets, all in one day.
