Universal Studios was great! On our last trip we went to Disney World, so now we wanted to go somewhere else and chose Universal Studios/Islands of Adventure! My personal favorite rides were the Mummy Returns Ride (new!) and Spiderman. What am I talking about--every ride was my favorite! At Islands of Adventure the one ride that REALLY stuck out was Jurassic Park. That was very fun! The thing, though, about all these rides is that the waits are hours long! What we did on the Spiderman ride was choose the "Individual Riders" instead of the regular line with families and people who want to go together and were on the ride in about 3 minutes compared to 1.5 hours! That was the only ride we did that on, though, because we wanted to be together for most of the rides (not recommended for families with small children, but it works great for teenagers and adults). One day we went to Universal Studios and the other day we went to Islands of Adventure because it will take a day to go to everything!
Almost all of the hotels and motels in Orlando offer free bus shuttles to and from them (a great perk, because we didn't drive our whole trip). It was great!
