I will be buying a multi ticket for my return trip from NJ in Aug. I am planning on taking the Penn out of Trenton to Pitts, then catch the CL into chicago and then take the Hoosier/Cardinal from Chicago to Indy. Right now I have priced it out using my AAA discount, but see that weekly Amtrak offers "weekly" specials of up to 25% off. So since my trip isn't till Aug 15 should I give it a few weeks and see if one of the routes I take come up avaialble on the weekly discount or just go with the 10% I am getting now?
