You may be just as well asking this question on the transportation board.
However, if you are staying on I-Drive, does your hotel proide any transport to the theme parks. We stayed at the Quality Inn last year and transport was provided to Universal. The last bus came back about midnight so we managed to visit CityWalk a couple of times. If transport is provided to Disney, then it's reasonably easy to get to DTD from the transportation centre at Disney.
