So in short I don't normally wake the aisle passenger, the possible exceptions is if there are wires everywhere and it's too dark to do it safely.
The other challenge (I find) is when the aisle passsenger crosses their legs atop one another. Still perfectly possible, but adds to the risk of failure somewhat!
