As mentioned above, both UndercoverTourist.com and OrlandoAttractions.com (and others) sell tickets for various numbers of days. You can get a 4 day ticket from them.

Please note that for a 4-Day Base ticket (or similar) you can buy either a Flexible ticket which can be used at any time but costs more. Or you can choose the date that you want the ticket to start and this will be cheaper. With the 4-Park Magic ticket you have to choose a date.

I'm not sure when you are going... but to give you an idea of price, a 4-Park Magic ticket (as mentioned above) starting tomorrow costs $334 (about £260) on UndercoverTourist. A 4-Day Base ticket starting tomorrow costs $406 (about £315).
