Since land space is so limited for expansion in Disneyland, I would do the following
1) Autopia Removal - Once the contract with Chevron expires in 2010, the Autopia should be removed. Yes, before anyone yells at me, Autopia is beloved by children and was one of Walt's favorites. But it does not belong in Tomorrowland. There is nothing unique about driving a mini car around a track anymore..since most amusement parks have them. Autopia takes up too much space.
2) Monorail rerouting: The monorail must stay but its track should be shortened. The curves in and out of Fantasyland and Tomorrowland destroy valuable space..how...future buildings cannot be built very high because of the beams. I would have the monorail stop at the existing station upon entering Disneyland.
3) Remove Innoventions: This attraction has never really been popular so I would remove it.
4) Remove Star-Tours: Unless it is updated, this attraction has lost its appeal.
5) Remove the Starcade and all the video games.
By doing all of this, new attractions can be built and valuable land space is once again available.
One new attraction could be an updated version of the Journey to the Center of the Earth attraction which is very popular at Tokyo Disneyland - Disney Sea park.
The following info is from the above link:
"Journey to the Center of the Earth takes you on a winding trip down to the earth's core. Along the way you will encounter crystal caverns, strange creatures, and a variety of special effects that make this attraction one incredible feast for the eyes. Often breathtaking, sometimes scary, you could ride this attraction dozens of times and still not see everything.
The attraction's queue is nearly as exciting as the ride itself. The queue has two parts. The first part has you working your way past makeshift laboratories with items apparently taken from previous expeditions. This queue ends at one of several large elevators, which transport you at high speed down below the earth's surface. The second queue takes you past huge drilling machines, giant electrical transformers, and other support equipment necessary for a journey of this magnitude.
The vehicles you ride in are pretty amazing themselves. They are large cars with giant shovels on the front, and look rugged enough to actually take you on a trip underground. The technology built into the cars allows them to travel smoothly at a variety of speeds, from slow, "sightseeing" tempo all the way to up rollercoaster quick. (I have read they are based on the same technology as the ride cars in Epcot's Test Track.) Although it gets pretty speedy at the end, the ride is never rough.
Journey to the Center of the Earth is one of DisneySea's premier attractions, and unless you have no tolerance whatsoever for thrill rides, this is a "must do" attraction. This is a fantastic ride that does not disappoint."
Any ideas for Tomorrowland expansion?
