Do wait until the last minute.
If you're vacationing this holiday, don't lug decorations from home. Hit the grocery store upon arrival to purchase fresh items from produce and floral departments. Tropical flowers last longer if kept in water and out of direct sunlight. Good choices include anthurium, ginger, protea, bird of paradise, and heliconia.
