There's the Red Carpet Experience, which is basically an overview tour of both parks and the Walk in Walt's Footsteps tour, which gives more of a historical background of DL. I've never taken one, though. I've been to DL more times than I can count and probably know my way around the parks better than a good many CMs so the first would be of no benefit to me and the second might be informative for me or I might know more than the tour guide. I believe both tours are $49 each.
