I think because of the locality of some posters we do get a biased sided view of where services are required and I think DP certainly falls into that.
Places like DP were not designed to be accessed by public transport, the original designer outlets were built on major road and motorway junctions because of the very reason that they wanted car users. Massive car parks, drive thrus, its not aimed at Beryl and her free bus pass. Royal Quays is fairly similar but is boosted by the ferry terminal and the large local population around
Look where Metrocentre is built, on the side of one the country's busiest roads. MC is a different kettle of fish admittedly but it was/is Gateshead's defacto town centre, almost a city of its own.
I'm certainly struggling to think why anyone but locals would decide to visit via bus (other than day out) as opposed to accessing Newcastle, Metro, DUrham or even Sunderland
