Almost exactly a year ago I was in Orlando doing exactly this. We never had any issue requesting cars with car seats anywhere in Orlando, to go anywhere in Orlando. We stayed in town, not at any Disney resorts.
Orlando basically survives on the tourism industry and there's enough demand there for Uber drivers to be available at most times.

I would suggest Kidmoto in Orlando and Port Canaveral and surrounding areas. They provide up to 4 child car seats in a vehicle. Front-facing, rear-facing and booster seats, all pre-harnessed and pre-installed. Try Kidmoto in Orlando.
