Hello Ian,
I'm just so thrilled to be assisting a Guest who hails from my home County of Cornwall, not to mention absolutely delighted to know you're planning a wonderfully extra long jolly holiday to Florida this coming August!
Your trip itinerary sounds practically perfect in every way, by dividing your Disney days into the 1st and last week of your holiday you're certain to get the best of both worlds.
Lucky Guests like you and I visiting Walt Disney World Resort from the UK benefit from the exclusive option to purchase great value for money
Ultimate Tickets, however as I'm sure you'll already be aware Ultimate Tickets are presently only available in 2, 7, 14 and 21 day options in addition to the current promotion (exclusions apply) of 14 days for the price of 7.
Unfortunately none of these options specifically cater to your particular needs as currently 2, 7 and 14 day Ultimate Tickets expire 14 days after their first day of use and 21 day tickets, 21 days after 1st use.
Perhaps you may like to consider purchasing 2 day Ultimate Tickets during 1 week of your holiday and the flexibility and convenience of a 7 day Ultimate Ticket in another?
If I can help sprinkle any extra pixie dusted advice onto your magical plans to visit Walt Disney World Resort this coming August, please pop back to ask me another question.
Have a great Disney day!
~ Jane
