We toured the Edison/Ford Estate on Dec 27,2005- a very crowded day with a 20 minute line to buy tickets from one very busy cashier. The parking lot, museum and laboratory are one side of the street, the actual estate is across the street on the water. Unfortunately the buildings have been extensively restored and now resemble new construction designed to look old- which is exactly what they are. You cannot go inside most of the buildings and nothing on the seond floors are available for viewing. Most of the rooms are seen through glass panels inserted in the windows.
If you are on a budget you should consider the $9 tour of the museum and then just walk along the sidewalk in front of the estates. You will see 90% of what you need to see.
The day we were there was so hectic that it was hard to find any of the staff actually checking any tickets at all, but I don't think that would be the norm.
Edison knew a good winter spot when he saw it! There is a lot to learn here too.
