While I love the benefits that come with being an AP holder at Universal, such as the free parking and discount on food/merchandise, there are more smaller perks that can be added.
One idea is an AP only line for entrance into the park. I think this is something that could cut down on the wait for AP holders, especially as many tourists spend ages trying to figure out which finger to use on the scanners.
Another idea is a loyalty program, which tracks how many years you have been an AP holder or how many days a year you go to the park. You can then get benefits depending on that info (such as express for a day, further discount on the onsite hotels, etc).
What are your ideas?
