My son and I are going in December and are doing all things Christmas! I wanted to spend a morning and early afternoon seeing the decorations at the deluxe resorts. That evening we would go to the Christmas Party. How long should I plan for this. BTW, we are staying at WL and AKL, so we do not need to figure in time for those! Also, is this difficult to do with bus transportation or should I rent a car for the day? TIA!
