We were just there in early January with our 2 and 5 year old. They do have a rider swap however it is a bit different then how disneys works. At disney you are given a ticket and can come back to use fastpass line at another time. At Universal you are not given a ticket. The younger child and a parent wait in a waiting area and then when first parent and older child done, they come get you and you go straight to front of the line. The positive of this was that if its raining or hot or whatever, you can be inside waiting in a small room with the younger child, the negative side of how this works is if your child takes a nap in stroller. Our 2 year old took an almost 2-2.5 hour nap every day in his stroller and for some of the rides you couldnt bring the stroller, so taking advantage of parent swap was then more difficult if he was napping. I remember that the harry potter ride and spiderman ride at Islands of Adventure both had a waiting room. Our two year old loved the Suess land. He loved the show, characters, and rides in that entire land! He is still telling me he wants to go on the "hat" ride. lol. There is also a play area in suess area that both of my kids enjoyed. At the Universal Studios side, my 2 year old enjoyed the barney show (and after the barney show there is a play area they can play in which my kids also enjoyed). There was also a curious george play area they liked as well. I'm sure every kids has different fears but my 5 year old while not scared at anything at disney or anything else at universal was terrified at TWISTER(my two year old was fine with it though lol.) The 5 year old had done all roller coasters and everything but only scared at Twister. Maybe because we actually have had tornadoes where we live so harder to remember it was pretend! We loved eating at Mythos, great food for adults, but also has kids meals with normal "kids" food. My kids really enjoyed the sushi dessert there (rice crispy treat/fruit roll up thing). The kids also enjoyed watching the Parade. If you have certain characters you want to see the most during parade ask a cast member and they will tell you best spot to be. My daughter told them she liked Dora the Explorer and they told us where to stand, and sure enough Dora stopped right in front of us for a long time. Have fun!
