Steve, I don't know exactly where you are in the Orlando area, but if you go to Winter Garden (West on Hwy 50) there are a couple of abandoned shopping center parking lots where you can plan to your heart's content.
Listen to what Carl, Diligaf and the others are saying....and go to the abandoned parking areas and just make yourself comfy with large circles, then smaller circles, etc. You will have lots of room and you will be amazed at how quickly it will start to come together.
A few years ago, when I lived in that area, my challenge was to take an autistic son of a friend on the autism awareness ride. I was very concerned about doing it so I met him and is mother at one of those parking lots on a Sunday afternoon and just played most of the afternoon with him on the back of my bike. By the time that the ride was held (the following weekend) he was comfortable on the bike and I was comfortable with him being there. It made for a great 15 year old birthday gift, and helped me as well, improving my tight turning skills.
Just trust yourself and your bike....you can do it. Believe me, if I can master it, you should become a super star in no time....lol
