I agree with Rosebud above. Universal is enjoyed most by older kids (teens) who are into the big roller coasters and thrill rides. I took my daughter to Universal when she was 5 and basically we just spent the entire day in Seuss landing while her older sister (12) and my wife went on the thrill rides. If you only have 4-5 days, just visit Disney. You can easily spend 2 days at MK and 1 day at each other park with a 5 year old and have plenty to do. It's best to read through the list of attractions at each park and decide which is most likely to appeal to your child. As another poster mentioned above, if you have a girl, you may spend extra time in meet & greet lines for princesses. With a small child, getting to the park for rope drop is a good idea and then leave late afternoon/early evening. Although, if it's possible, the Wishes fireworks are great for any age. Perhaps stay out late your last night for Wishes?
