We happened to be at Universal during a Christian rock concert weekend. It made it over all busier, but they also kept the place open until 1am. For an additional $25/ticket we could add the evening on, so we did. By 10pm we had the place to ourselves. Everyone else was listening to music. It ended up working out great. And we slept in in the morning which was also nice. This is Hagrid’s motorcycle in Diagon Alley.
