I've used a combination of both on hols before, with a small selection of cloth on a heavy rotation. If I had to handwash I wouldn't bother.
And I wouldn't be hidebound by using eco disposables either - most of them aren't that "eco" and if they go in landfill then they won't degrade in any event. IMO you do enough for the environment using cloth 50 weeks of the year so you might as well use the good sposies on the odd occasion you need to indulge
