Given the choice between floating into scalding hot coffee when the ship stops accelerating or a rotating section I know what I'd choose... Full on artificial gravity.
If you don't like rotating sections then perhaps consider the rotating ship. An idea I got from a Heinlein book, essentially the enire ship 'rolls' along. No friction or bearings to think about, full gravity for the whole ship (admitedly variable strength, but you can't have everything) it seems clever. I haven't put that much thought into practical issues, but none are jumping up at me right now.
