The TSA recently announced some security changes at Orlando International Airport, and they seem to be going into effect now. What is changing is that ALL electronic devices (including, but not limited to, tablets/iPads, computers, laptops, cameras and game consoles) that are bigger than a mobile phone need to be put into their own tray. So you could end up with quite a few trays all to yourself. What's also changed is they are asking if you are taking on any food (including chocolate and sweets), as they'll want to do security checks on that, too.
They have advised that you arrive an extra 20 minutes earlier (so 3 hours and 20 minutes now for us, technically), due to the extra backlog of people this will create going through security. If you've already got transfers booked and are worried about timing, you should get in contact with your travel agent for advice and find out if any action is necessary.
