I wouldn't be opposed to the idea of Luke's X-Wing entering Tattoine's orbit and landing near Ben's Hut or something like that. Don't know if the Falcon would have been parked there either. Oddly enough if both ships were parked out in the middle of nowhere, there would have needed to be security present just so the Sandpeople don't raid them. Perhaps it's better that the ships were left in Mos Eisley after all then. Now this is of course whether Luke's visit to Yoda does end up being pushed to the start of the film however.
