We've done this walk from the DTD bus stop and it is quite enjoyable, we go early evening on the first day, it gets our legs in the walking mode for the week. Others say Goodings prices are high, we didn't feel that way. We like to pick out what we want and see the stuff so we don't do delivery service and the fee for delivery is more than the higher prices of Goodings.
A better tip to save some cash and back ache, bus to DTD, walk to Goodings, you're arms are empty then and after you shop, depending on the amount of groceries you buy, get a cab back to the DTD bus stop or your resort, cabs have a min. like 2.00 just for sitting in them then the meter starts.
