It's hard to say. When I was there last, we didn't have express. Around 7pm we were able to walk on pretty much everything except Ministry of Magic (We went during Christmas and waited 5 hours for this ride. I am a huge Harry Potter fan, so I had to do it.) We did wait 30 minutes for Donkey Kong Mine Cart but went into How to Train Your Dragon area and everything was pretty much walk on. Both parts of the park have tons to do, so it is just really how much time you would want to spend in each and what time of day you want to see it. How to Train your Dragon area can get pretty dark during the night.
