After reading the entire blog hop (which I LOVED...thank you for that

), I am starting to second guess my pre and post race plans.
On the day before the race, my mother-in-law, sister-in-law, and I are planning to get up around 8:30 and head to Magic Kingdom. We want to have lunch at Be Our Guest, ride a bunch of rides, have an early dinner in the Castle, and then head back around 6:00 for some shut-eye. My initial thought was that we wanted to be tired early, and walking around the park would help us get some sleep; however, now I'm wondering whether we should take it easier that day and rest our feet. We have a Castle reservation though, and that would be tough to get on a different day. Am I crazy to do MK the day before the race?
Also, on the day of the race, we plan to take it easy, head back to the resort for some hot tub time and napping, and then go to Downtown Disney for dinner and the Happily Ever After party. We figured we would probably be tired, and we didn't want to push ourselves too hard; however, now I'm wondering whether we will feel excited and want to go to a park for the day. I'm also wondering if we should book a lunch/ brunch somewhere instead of our dinner. If so, what time would we even book it?
Can anyone who has run this before tell me what you think about pre-race and post-race planning. I am really not sure whether to change our plans or keep them. Also, I really don't want to be changing around fastpasses when I'm there, but I'm totally okay with changing them from home. We only have 2 1/2 days worth of park tickets (the half day is pasta in the park with extra Epcot magic hours), and right now we are planning on going Fri. for pasta, Sat to MK, and Monday to HS.
What would you change/ keep? Thanks!
