I'm not sure the number of prospective jurors called per day will indicate much. In my personal experience, when you get a summons in Orange County, you are instructed to call in to a special number after 5 the night before and they list a range of numbers on the message. If you are not in that range , you do not have to report. So, the number of summons sent does not really indicate the number of people who are required to show up.
There are are probably a lot of people in Central Florida right now with summons who are sitting on pins and needles.
FWIW, has anyone considered Inverness? It's a short drive up the Turnpike and pretty removed from Orlando.
