Actually depending on your software, if you're a diehard imager you'll soon reach the point of not ever doing 1, 2 or 3 star alignments. Most modern astrophotography software will incrementally adjust your pointing to your chosen target through plate solving.
You can do a single alignment at the start of the night, but its not really necessary. Most packages will fail over to a "blind" solve if the inital field solve fails.
Mastering plate solving is an awesome step up and definitely something to start playing with if you haven't already.
