I am all about Scandinavia getting a make over starting at the front gate and working its way in. I would say gut that entire area - including the Tivolis and redo it.
A new Guest Relations building, new ticket area, new entrance gates, and then put the Tivolis over the hill on that level ground near the Orient's lot. You know how there are stairs from the bathrooms down to that level area. Build a double decker building there and get rid of the Tivolis. That will open up that area for a huge front gate. Also need new front gate Emporium shop and so on -- maybe a TGIFridays or a Red Rockets there as well?
Hmm.... lots of possibilites!
