Based on the replies it seems that a lot of people remove many inspection panels and screws before they re-install them.
I always open up one area, do the inspection and then close it back up. There are a few areas that have many screws (empennage area, seat pans, baggage wall) but I always open up each section and re-assemble before moving on to the next section.
I also like to spread the inspection out over a few weeks. I will often do a flight after doing an inspection that requires a lot of dis-assembly & re-assembly. I feel that it reduces the chances of having a maintenance induced problem.
