You might be better off with a seasonal pass? I didn't see when you are going to Universal? First off the AP's are park hoppers which is useful. Seasonal passes have black out dates so that might not work for you. The big advantage with an AP is you get a good room discount at the high end express pass hotels making them pretty reasonable. The numbers work much better for me since we are a family of 4. In my case it's much cheaper to book the high end hotel with everyone getting an express pass as opposed to staying in a cheaper hotel and buying 4 express passes. Express passes are not cheap at all.

The 5 day 3 park ticket is a pretty good deal. BTW usually you get 10% off for a using an Amex card. Not sure if they will do that with promotional tickets? With 5 days I would do the one park a day tickets. Depends on how much you want to spend.
You have many options some dependent on the time of year. Personally I have never bought an express pass and probably won't ever. I have used them because they came with the room and can cover many attractions quickly if you want. We showed up at 3:30 to check in and we headed right out to the parks, we literally finished a park by 8:00 closing then headed to City Walk for dinner. We did everything we wanted to in that park. 5 days with express passes is actually over kill if you ask me. Even 2 parks in 3 days won't need an EP.
Another option is you can always add EP to your tickets while at the park. If crowd are heavy maybe spend the money the last day getting an EP and hitting everything again that you liked? Many many options. LOL. Good luck.
