Shoot your scenes out of order. If a dance hall is cheaper to rent on a Tuesday than on the weekend, then film the dance scene on Tuesday even if there are a bunch of other scenes before that one that have yet to be filmed. If your ending scene calls for a lot of explosions and the pyrotechnic technician is only available for the first week of a month-long shoot, then film the ending scene first. Editing allows for you to film whichever scene you like whenever you like and is convenient.
Film all the scenes that use a single location in one go. If you have three scenes by a pool, then shoot all three in one day, even if the scenes occur at different points in the story. You will not know whether the pool will still be available later or that all your actors can make it back to film a pool scene at later dates. Get as much work done as your can at a location in order to protect yourself and your film from unforeseen difficulties.
Split your film crew and actors. If some actors do not share a scene with any other actors, then you can record them while the other actors are filming other scenes. You can even do this for individual shots if you are careful about camera angles although it is easy for this shortcut to look cheap and for the audience to catch on if you do it too much.
Film early because lighting a set at night can get expensive, especially if you are away from civilization. Generators are the lifeblood of all film crews, but they can require a lot of fuel if used continuously and take up a lot of space in your trucks. You also need to be aware that accidents happen more often when people are tired, and filming late at night only exacerbates this tendency.
