Thanks for stopping by the Disney Parks Moms Panel, Heather!
Where else can you eat at a restaurant where Lady and the Tramp had their very first kiss!?
While grabbing a seat near the parade route might be challenging, I would highly recommend making the request upon check-in for your dining reservations. As you know, parades take place daily at Magic Kingdom Park so you'll want to check out the schedule to see if your reservations match up as you never know what might be available.
Otherwise, for an extra-special guaranteed viewing experience, you can reserve a
Disney Festival of Fantasy Parade Dining Package that includes lunch at
Tony's Town Square Restaurant followed by a reserved VIP viewing area for the parade. I just checked your arrival date of March 30th and it looks like there are still a few tables available, so if this option sounds like a fit for you and your family, I would highly recommend booking as soon as possible.
If you have any other questions, please let us know. Have a magical day!
Oh, and of course I would recommend the spaghetti and meatballs.
