Hi Rob!
Welcome to planDisney.
It's always a pleasure to assist my fellow guests from the UK, so thank you for sending in this question - I love the idea of 8 weeks in Orlando!
You are able to purchase a Disney Incredi-Pass (Annual Pass) but this can only be done once you arrive at Walt Disney World. Visit any Ticket Window at a Disney theme park or water park (Disney's Typhoon Lagoon or Disney's Blizzard Beach, whichever is open) or if you are planning to visit Disney Springs on your first day or so, you can also buy tickets at the
Ticket Center there. Please remember to take valid photo ID with you (UK passport or driving licence will be fine).
While no start date can be set in advance, your Disney Incredi-Pass will only become active from the first day of use when entering a theme park. This will also be perfect for your trips because no block-out dates apply to this annual pass.
As I don't know your arrival date, the current cost of an adult (ages 10+) Disney Incredi-Pass is US$1649.69 including tax. If you add
Disney PhotoPass Downloads and
Water Park and Sports Option, that will cost an additional US$99.00 each, the total for adding both would be US$1860.56 including tax.
All prices are subject to change.
Please come back and visit us if you have any further questions, and you can
send me a direct question if you wish. We are always happy to help you plan your magical holidays at Walt Disney World.
Sue
