make sure you have a generator/electricity to charge the thing up! Would be tough to take it in the trailer and not be able to find an electricity source. Gasoline carts can be bothersome with the noise, etc. Same with ATV's, etc. I would go with electric, if you felt you had to have one.
I trailer my car all over the place and have never thought about a 'tween transportation situation. We just walk around the paddock's, etc., and around the big parking lots.
Now if somebody was older, or elderly, or had health issues I guess a cart of some sort would be necessary.
Let's get some golf carts on the track at run n gun! fun!!!!
