Tinkfan, you will LOVE July 4th. We were at Beach Club Villas and Old Key West last July 4th week, and we had a ball. It was very busy, and on the 4th we decided to skip the parks -- just swam and relaxed. But the high point of the trip was definitely the fireworks, which we watched from the beach at the Polynesian. There was so much color and you literally didn't know where to look, because so many fireworks were exploding at once. You will have a perfect viewing area in the Polynesian concierge lounge. Have a great trip!
See you at WDW.
