We are heading to WDW on 12/11. 1st DS will be 4 and 2nd DS will be 9 months old when our trip comes around. I made an ADR for 12/11 (our arrival day) for dinner AFTER the 6:30 showing of Fantasmic! I'm wondering if I should cancel the ADR since it's our travel day and I'm worried the kids might be over tired. Is it worth the risk?
