Considering this was a fairly small project, the future isn't looking bright for the expansion of Legoland Windsor unless Merlin offer to pay towards improving road works
The expansion isn't necessary. My personal opinion is that the park's priority should be improving park operations (especially throughputs!), and updating older areas.
Updates of older areas work has begun already - Pirate Shores (2014) and Kingdom of the Pharaohs (2009).
Yes, the expansion would have been great, and would have brought me back to LEGOLAND, but if I started hearing reviews highlighting improved park operations, I'd head back.
