We are visiting Universal Orlando in July (9th and 10th) and staying on-site so will have Universal Express. I've never been to the parks before and am not sure what to expect in terms of wait times with the passes. Is it truly close to front of the line, or do many rides have waits? Which ones are likely to have say 15+ minutes of waiting? Transformers? What else? Lastly are there any rides that are potentially worth waiting in the regular line due to theming that you miss with the Express version of the line?
