We just did the same exact thing on the 1st of July . We stayed 3 nights inside of Disney and drove over to Port Canaveral on July 4th to sail on the Sovereign. Just like the last person said , I would try to stay inside of the park. The All Star resorts are all very reasonably priced and you can get into one of those for the same price or sometimes a little less than a hotel outside the park. We stayed at the Contemporary resort because of its location beside of Magic Kingdom. We knew that 3 days was going to be cutting it a little short at Disney with all they have to do and see so we booked here. A little more expensive but well worth it because of its location. We drove to Florida so a couple of nights we drove outside the park to have dinner and from what I seen with other hotels , they all look very nice. Didnt see anything that was run down or anything. Hope this helps. If you need anymore info just let me know.
