On our DHS day, we're doing a late lunch/early dinner TS meal for this reason.
We'll eat a CS in the morning prior to opening at our resort. Be to the park at opening....Grab a snack around 11am or so....Then we're heading over to Beaches & Cream at the Beach Club for our early "dinner". Since no ADR's are taken, we're getting there early in case we have to wait but hope to eat around 3:30pm...Then we'll head back to the park, see a couple characters, use a couple FP's accumulated earlier, and then head to the F! line. Likely we'll grab a couple snacks for before/during F! as well.
No CS for us in the park that day.
