Ashland,
We did try costco. And correct, because we arriving late we are staying near MCO. We looked at shuttles, Uber & nothing comes close to the car rental in terms of prices. We used the Hertz/AAA site, seems they are having a hard time renting electric vehicles. SO we are getting a HUGE bargain. And they are waiving the car charging fee with my company's Hertz discount code, they let us combine.
