We got Uber from MCO to iDrive but the only option was UBERSelect (We were told to go to the tunnel underneath the arrivals terminal for pickup) and the cost was around $44. Still a much cheaper option than a town car and cheaper than Mears by at least $10 I think - it was a lovely big car/extended SUV (Cadillac Escalade) that picked us up. For comparison, the prices from iDrive (near seaworld) back to MCO was UberX=~$16 and UberXL=~$24. We used UberXL as we had a fair amount of luggage between the three of us and a normal sized car might have struggled.
