I do the ones that require pictures of the room and bathroom before I touch anything and of any problems, and maybe of the lighted signage at night, pool, exercise room, uneaten meals, front desk area, etc. You just do some pix as you walk to or from the bar, to or from breakfast, etc. Maybe about 15 pix on a one night stay would be the max I have EVER done, but that was where there were a lot of problems to document.( Did about 30 for a 2 night stay at a high end resort with many extra interactions (dry cleaning, cash left in room, coffee kiosk, sandwich hut, pool service, spa reception area and dressing room, etc.). It's just a matter of getting into a rhythm. I still have time to put my feet up and read or watch TV and still depart with only the departure interactions to add to the report.
I would not do a shop that required 70 pictures. Period. Why bother when there are so many that are a lot easier.
