From Cheshire Figment's ticket sticky at the top of the boards (and there is a new deal out for Florida residents as the PP mentioned that is not discussed here):
Tickets Available Only to Florida Residents
Almost all MYW tickets are discounted for Florida Residents. Proof of residency is required when purchasing tickets, and upon first use. This includes the showing of a government-issued photo ID such as a Driver's License or state-issued ID card.
The cost for a one-day base ticket is not discounted at the gate. There is a small discount for online purchases in advance. However, the rates for the Hopper and WPF&M options are set at 50% of the non-Florida prices.
There is no two-day ticket available. However, the three day "Play Three" costs less than a two-day base MYW and the four day "Play Four costs significantly less than a three-day base. The Play Three and Play Four tickets are valid for 180 days from date of first use. The Play Three and Play Four tickets may be upgraded to additional days, but the additional days will expire 14 days from first use unless the No Expire Option has been purchased.
There are three special types of Annual Passes for Florida Residents.
The "Seasonal Pass". This is a park hopper which is valid about 260 days of the year. The block out dates tend to be a week on either side of Easter, a week on either side of Christmas, and most of the summer. This pass does not include free parking at the major parks.
The "Epcot After 4:00 Pass" does include free parking. It is primarily intended for local residents who would like to dine at some of the Epcot restaurants.
The "Water Park After 2:00 Hopper", since the water parks do tend to empty out starting in mid-afternoon, this is primarily intended for after school use.
