Hi there! First of all, are you absolutely certain you want to do an MK park day on top of the party? I know people do it, but it has always seemed over the top to me. And I am totally obsessed with MK! If that is to be your plan, though, I would say you have picked the best spot for your main meal of the day. What about scheduling it a bit a bit later, though, maybe 4-30 or 5 ish? This could let you relax and eat during that transition hour where the day guests are starting to migrate out and party guests are flooding in. My daughter and I did this for the first time last year, at Columbia House, and not even because we planned it... but we found we actually want to escape the throng of guests making their way <ahem> reluctantly toward the exits.
Our normal strategy, since our first multigenerational
MVMCP (ages 3 -89!) has been to enjoy a late breakfast and alternate activity in the morning, followed by a good 2 hours of down time. Not necessarily a nap, but books, movies, video games, poolside loungers, whatever appeals. Then a hearty sit down meal. We even cooked a "Christmas dinner" in a vacation home one year. We are at the gates for 4 pm, and from then on, we just take breaks for food when the mood strikes. We love the party specialties, and Sleepy Hollow waffles are a great "dinner" -pumpkin spice ones, if I am lucky. No need to be hungry, despite the food selection being smaller.
The long and short of it is that We try to get in good servings of fruit, veggies, and protein earlier on a party day, then snack as the mood strikes throughout the evening. It has worked well for us.
Very excited this year, as we are fulfilling a fantasy-
MNSSHP on Halloween AND just changed our return flight so we can attend the first MVMCP of the season!!!!
