While I'm delighted at the news (I exclusively drink Starbucks at home and at work), I don't read the announcement as saying that Starbucks coffee will be replacing the Nescrape' currently being served.
I don't mean to pour cold coffee on the celebration, but the
Disney blog post mentions that there will be "six planned Starbucks locations" in both
Disneyland/CA and WDW. So, while I'm still happy that Starbucks will be available, the announcement only says that there will be one Starbucks location per theme park.
But I can still dream. And you can bet i looked to make sure the date of the story wasn't April 1.
