As they say in the wilderness, "
Howdy Adam!"
Disney's Fort Wilderness Resort truly does hold a very special place in my hEARt as I've been lucky enough to have stayed there several times with my own family in the home-sweet-home-away-from-home 
Wilderness Cabins.  We love everything from the comfortable, yet outdoorsy vibe, to 
The Fort's close proximity to the enchantment of the
 Magic Kingdom Park.On your behalf Adam, I've taken a quick peek at the current 
Disney's Fort Wilderness Resort and Campground - Vehicles, Carts, and Recreational Devices - Rules and Regulations, and although I can see that private golf carts must indeed be 
golf-style carts, and 
not off-road, ATV, utility, or construction type vehicles; there are no specific rules pertaining to gas-powered golf carts.  
However, I am able to share that neither gas-powered scooters nor motorised dirt bikes are currently permitted at 
Disney's Fort Wilderness Resort and Campground.
Adam, in my own personal opinion, I would either opt to bring an electric golf cart from home, or perhaps enquire with Cast Members about the current availability of
 Golf Cart Rentals - 4 Seat at Disney's Fort Wilderness Resort and Campground.  It's fairly straightforward to 
connect with Cast Members to discuss Golf Cart Rentals by dialling the telephone number contained within this link.I hope that I've been able to provide a little pixie-dusted insight for you today Adam.  If you should have any further questions about your upcoming zip-a-dee-doo-dah April vacation to the most magical place on earth, then please do mosey along back to
 me here at planDisney.Have a great Disney day ~ Jane
