After spending some time apart on separate coasts, estranged couple Courteney Cox and David Arquette reunited at DIsney World in Orlando, Florida ... and 6-year-old daughter Coco looks like one happy little girl!

After snapping this photo in front of Cinderella's castle, David tweeted:

    "Disney World really is the most Magical Place on Earth."

Cox, 46, and Cougar Town co-star Josh Hopkins, 40, spent a recent vacation together in St. Bart's, however a rep for the former Friends star said their relationship is "strictly platonic."

David and Courteney separated last October after 11 years of marriage. Although they're not together romantically, the duo have teamed up on the big screen, yet again, for Scream 4. See them working together ... after the jump.
