Poly is the most convenient of all for transportation, I feel. But "reasonable" option for a washer and dryer means that I wouldnt stay there more than 3 or 4 days max. I quite like SSR. We thought it was tranquil and now with Disney Springs redo, its kind of a good location. So if it were me, id make the choice based on how many in your party. If its 4 or less and since its only 4 days, I'd say poly FOR SURE. 5 or more, SSR NO QUESTION.
