Hi
There are 2 I think, one at Osceola courthouse in Kissimmee, and one in downtown Orlando.
We went to Downtown Orlando.
We were staying on international drive before the wedding and din't have a hire car, so we took at taxi from our hotel, he waited 30 minutes for us whilst we went in & got it, and then he took us to Disneyworld to start our week there, it cost us $90.
I am not sure of the distance from Disneyworld to Kissimmee courthouse, maybe someone else would know, but I didnt think $90 was bad as we were using him for a good hour and more.
