Narrative:

Cross country to orlando from tpa entered tfr, hard to define the exact start of disney world to see how far the center extend from exact which point. I called orlando approach from guides, but when they answered after my third call I had already entered tfr inadvertently. In a helicopter with no navaids it can be hard from 500 ft AGL to see the center of an area covering many square miles as disney world.
