The most bang for your buck is to buy the least expensive annual pass, the weekday select. You get free parking and discounts, plus parkhopping, things that all cost extra with the cheaper tickets.
Starting in January they usually have some kind of 3 day or 4 day deal for Florida residents. These are usually good through the early summer.
What I have done in the past is buy one of the deal passes, gone on the weekend, then upgraded it to an annual pass.
Another strategy for a Florida resident is to just go to a hard-ticketed event, like after hours or a Christmas or Halloween party.
