My family of four (two teenagers - 13, 18) will be going to Disney for the 2nd time during Christmas week - 1st visit 2000. The first time we spend the entire week at Disney. Is it too much to try to see the two Universal Parks, and Seaworld in addition to enjoying time at Disney? We'll be arriving Sun 12/25 and leaving Sun 1/1. I assume we'd need a day in each place (minimum)??? I just don't know if its worth it to try and see it all with only 7 days during the busiest time of year. The kids want to do MK, AK, Epcot and MGM too!!! (At least I figure this time they'll know what rides they want to see and we wont be in line for character autographs) What do you think?
