Obviously, Walt Disney is the reason anyone really goes to the Orlando/Kissimmee area and I must confess that Walt Disney World was the reason we took our boys there. We really enjoyed both Disney parks (Magic Kingdom and Animal Kingdom). We knew that Universal Studios had a park in Orlando, but we really didn't plan on going. When we reached our Resort, Silver Lake, we were given a discount on two-day passes to Universal Orlando just for attending a 90-minute presentation on their resort. We had a wonderful time exploring the streets of San Francisco and New York, and even took a boat ride on Amity Sound. Of course, the trip took an unexpected turn, but I won't tell exactly what happened. If you decide to go, though, I'll give you a hint. Don't sit on the left side of the boat unless you like water.
Quick Tips:
If you plan to see all of Walt Disney World, plan to take a two-week vacation. Even with the minimal crowds, we didn't cover all of the Magic Kingdom or the Animal Kingdom in the two days we were there. Each park had more than we could see in a day's time. I would suggest at least two days/park. I would also suggest resting for at least 1/2 a day in the middle of the week, especially if you have children, to help restore your strength.
Silver Lake Resort is great for this. Their pool with poolside snack bar is the perfect way to relax with the family. At Universal Studios, we took two days and saw everything in that portion of the park. It was perfect for the boys, too.
If you are planning to go during the summer months, I suggest getting a map and planning exactly what you want to see before going as you'll not be able to see everything in each of the parks in one day, especially with the additional wait times.
The Express Pass is available at all Disney parks and you should definitely take advantage of this option to reduce stress.
Best Way To Get Around:
The best way to get around by yourself is to drive. Silver Lake Resort also provides a shuttle, as I'm sure other resorts in the area provide. Since we chose to use our car, I am not sure of the schedules, but I'm sure they would help you at the front desk. Also, Silver Lake is only about 1 mile from the entrance to the Animal Kingdom, if you know the backroads. Again, just ask at the front desk and they will be happy to help you.
