Help Needed: Ideas for 2yo on car trip to WDW

[msce2]

We are going to be driving to FL from PA. We are splitting it so that we are spending about 8 hours (driving time) each day. I have plenty of activities for my 9yo and 5yo, but I'm wondering if anyone has any tried and true ideas for our little guy. We do have a dvd player but I'm thinking his attention span is only going to be so much.

Thanks in advance!
