I think the comment is Ironic /wishful thinking as nothing is happening on site.
Most of the focus is on the Corvera airport saga, which I believe is a precursor for any theme park announcements as it is so close. This assuming that they can raise the finance ( big assumption).
However, things in Spain are on the up house prices have bottomed out and are on the way up, international finance is buying up property from Bankia( the toxic bank) and the economy is doing well ( second best in the Euro zone) so that may mean investors are more interested in the project.
I still think it is a better idea then building one on the side of the muddy Thames, the weather is better to, today :-
London 8C day and -1C tonight
Murcia 20C day and 8 C tonight
I know which one I would like to be on doing 60 MPH on a roller coaster!!
