The golf courses as a rules in Florida are very well priced except for January to the end of April which is when the snowbirds arrive in Florida and this puts the price up so a good place to get a great deal is from GolfNow.com .
GolfNow.com is a web site that offers cheap tee times from course all over the USA so all you need to do is register on the site and the select Florida/Orlando and you will see an up to date list of the current offers.
If you find a tee time you want all you need to do is click on the time and hit the book now button this then reserves the tee times for you for a small fee which I think is about $2 per booking, you will then receive an email with the date, time and price you paid which you take to the course with you on the day.
Once at the course you will pay the green fee listed the email regardless of there current rate.
This is a great site and I have used it many, many times.
