This is our first time to Universal. We have 1 day, and are staying at Hard Rock, so we will have early access to IOA and fast passes. We have 4 adults, 1 7yo and 1 5yo. Wanting to focus heavily on Harry Potter, but definitely interested in Transformers and Spiderman/superhero stuff for 5yo. Can the app create a plan for 2 parks in 1 day? Where do we start, what can’t we miss?!
