Unfortunately, the day I want to buy the champagne, we will be at Animal Kingdom during the day, then leave and go to Poly for photos, eat dinner and watch fireworks. I was hoping to be able to buy a cold bottle from the gift store or counter service restaurant. And wanted to get an idea if it would be cost effective. BTW, if I were to buy drinks from the Lounge would I be able to take them out. Maybe if it were possible we would buy a drink then walk out to the beach for a toast under the stars and magic of Wishes. Any advice?
