I can confirm what others said about Pepsi and Coke living together in sin at Disney. I have an old wall-size map of WDW's Magic Kingdom from sometime in the 70's, and some restaurants have Coke and others have Pepsi. I would like this. I know it's different in different areas of the country, but here in Central Florida, it seems like Coke has a monopoly on the theme parks and restaurants. Sea World was the last holdout, but eventually they, too, switched to Coke. I like both Coke and Pepsi products, with a slight leaning towards Pepsi (Mountain Dew!), but I would like to see more variety when going to the theme parks.
Coke even took over the local Subways. There was nothing better than a meatball sub with a Mountain Dew! Now I have to have the sub with Coke.
