Imagine the reaction if someone proposed building something like that in the UK :lolol:
Both in terms of the scale (who'd want that in their back garden) and in terms of the in-your-face religious message.
Would never get past the planners.
There's already at least one religious theme park in the US: the Holyland Experience in Orlando.
Not sure it's quite up there with Walt Disney World in terms of popularity, but apparently the water they serve with meals is sensational.
