Just to let you all know, http://www.themeparkticketsdirect.com
has some special offers on at the moment. However you must book by 5th May 2008 to get them....
Disney 14 day Ultimate ticket = £159 Adult
Disney 21 day Ultimate ticket = £175 Adult
Orlando Flexticket 2008 = £110
Orlando Flexticket PLUS 2008 = £132
These are really good prices and the cheapest I have found for Disney and Orlando Flextickets.
I've used themeparkticketsdirect.com in the past and they deliver actual tickets usually within 14 days of booking.
