I agree, it's a very good time to go.
The weather will be hot but not too humid, with little rainfall.
Crowds shouldn't be too bad either.
The only thing I would say is that the weather in Florida is getting more and more unpredictable.
When we were there in March the average temps was supposed to be around 80 degrees, however, most days it was struggling to reach 70 and we had a lot of rain (not the thunderstorm Florida type, the British raining all day type).
Hopefully it will be better when we go in August.
Overall I would say October is an ideal month though, not as easy for us with school holidays etc
