Need restaurant coupons for I95

[starwood]

DS has been accepted into the Disney College Program starting in January. So it looks like we will be driving down several times that I hadn't planned on (1 to drop him off in January, 1 to pick him up in May and probably 1 or 2 times in between). I'm trying to find restaurant discounts for along I95 to save some money. Luckily we have a Prius so gas is only around $60 each way and DH has lots of hotel points to use. I'll probably pack food for the first day going down for snacks and lunch but that leaves 2 dinners, 1 breakfast and 1 lunch.

I signed up for Denny's. Any other ideas?
