There's a breakdown of rates on the Universal website, right here:

In addition, you also gotta consider using the APH code for any available AP discounts, and if you are a Florida resident, you can also use FLO. There are times when only one works, since they set aside a block of rooms for the promotions. Keep in mind, if you book under either of these, you will have to show proof upon check-in.
There's also other factors affecting the price, like number of guests per room, if you're staying on week days or weekends, and also length of stay.
Hope you're able to get a good deal and have a great trip! :thumbs:
