Neither. Do not do a sit down dinner for
MVMCP - you'll miss party time while eating. Do lunch at LTT instead and then grab CS for dinner before the party starts - it will be quicker and you'll have more party time to use for actual party events. (Make sure to prioritize the actual party events and get to them early so you have a spot - worry about rides after you've done everything else first, the park is open late and the rides will be walk on after the last fireworks/parade most likely.)
