We already have train tickets for our Feb trip from Boston to Orlando. We bought early without any discounts because if you want to get a sleeper which we wanted you want to be the first one buying because everytime someone buys a sleeper the price goes up. Our price with only the
AAA discount for 2 adults and 2 kids round trip with a deluxe sleeper for the NYC - Orlando leg was $970 but we are traveling during a peak time.
I have been doing a ton a research for this train trip because this will be my family's first train trip. (I took a train from Moscow to Leningrad when I was staying in the Soviet Union in 1987, but that doesn't count.

)
From what I understand sleeping in the seats work well for adults, but not so well for some children. You need to judge what your child needs to be able to fall asleep.
Here are some of my favorate train web sites where I have done my research and read trip reports and stuff.

There are others just poke around and see what you can find.
Tips I found about sleeping in coach.
Amtrak doesn't supply pillows or blankets to people in coach...so you should bring a warm thin blanket...Amtrak sells them on most trains in case you forget. If you need a pillow to sleep look to find a inflatable one before you go or just pring a pillowcase and fill it with your sweater or other piece of clothing instead.
Coach seats to recline.
You might want to bring music with headsets to fall asleep to to drown out the train noises when you want to sleep if you are a light sleeper.
Tips I have found about traveling with Children.
If the adults become cranky and frustrated with the time that train travel will take so will the kids so look at train travel as an adventure.
Bring small games and coloring books and stuff for you child and bring extra for friends they make on the train.
Bring a small cooler of your child'd favorate snacks because sometime the snack bar runs out of stuff and if your child is a picky eater you want to have on hand what your child will it just in case.
For the most part that is all I can think of right now to share if you have any direct question I might have the answer or I might be able to poke around and find the answer. (I am begining to become obsested with train travel like I am with Disney.

This weekend we taped out the size of the deluxe sleeper on our living room floor and taped out the size up the bunks. All four of us played in our pretend train room all rainy day.
Oh yes Hertz has a deal with Amtrak they will pick you up and take you to their downtown car rental agent when it is open or to one at MCO when the downtown one is closed. I found that with my AAA discount and AAA coupons Hertz is as cheap or cheaper then any other car rental place and they let you drop off their cars right at the train station...their is a little box inside the train station where you leave the car key. So to me not to have to leave WDW before I really need to I most likely will be going with Hertz.
Sorry how long this turned...I guess I had more info then I thought.
