I need some help getting my mom sister and her 3 kids from Hammond IN to Pontiac MI on Dec 28th to Dec 31st.

Best I can find online is
350 wolverine 5 guests $98.00 there on the 28th
and
353 wolverine 5 guests $98.00 return on the 31st

Is there any sort of promo code I can use that would bring this down a bit price wise?

If I book this and later find in the hot deals section of amtrak.com a better rate will they work with me on that or ?

I want to book this asap to reserve the spots, but want to try and find the best pricing too.

Also questions about the 350 /353 wolverine, I only rode one amtrack and that was from Chicago to New Orleans, it was awesome, sight seeing car, snack car, BIG long comfy seats (im 6'6') and still had TONS of room etc.

Is this 350 wolverine route train as comfy seat/room wise and do they have the glass top sight seeing area? I did see it said snack car though.

Thanks for any suggestions or codes or anything that might help me get this booked up for less $.
