Wheelchairs or electric carts in MCO?

[paras4ri]

I'll be traveling with my IL's next month and we're taking Southwest from Orlando. My FIL uses a walker and I'm researching options for getting out to the boarding gate. A Southwest rep told me I could get a wheelchair from a skycap but I'd really like to get an electric cart for him if possible. We're taking only carry-on luggage and I don't think I can manuever that along with pushing a wheelchair.

Any advice is welcome!
