Other ways to get yourself noticed:

Wave your arms madly in the air, preferably on a downhill slope, and preferably with vocal accompaniment (e.g. screaming)

Wear a novelty disguise kit (the ones with glasses, false nose and mustache are preferable): people will notice you, but won't recognise you if they see you again (also a good backup plan for aforementioned bank robbery)

Shout: "look out, cripple coming through!"
(I only use this term to describe myself, not others, and even then only in jest)

Shout: "How do you drive this thing?!" whilst careening down a hill

Shout: "Is that bit meant to come off?"

Mob one of the Year of a Million Dreams' CMs for their uniform - you'll get a whole entourage of stalkers in no time

Rig up a stereo system on your chair /
ECV and play loud music from it

Use aforementioned stereo to announce that a special surprise parade will be coming through soon, then just take to the road as everyone runs to grab a space on the curb.

Attend the MGM Jedi Knight Training School, then use the force to clear people out of your way

Steal the AT-AT walker from outside Star Tours, and use that to cruise around the park

If you can't get the AT-AT walker, steal a parade float instead

Don't pay too much attention to where you're going: once you've run over a couple of people, news of you will travel fairly fast.
