I'm no town planner but it strikes me that a one way system along the prom might cause fewer hold ups with two lanes for parking, one lane allowing drop off and one lane no stopping( except for zebra crossings of course). Instead of cars parked on both sides of the road, they would park at a slight angle on the hotel side but at almost 90 degrees to the road so no parking places were lost and vacant spots would be easy to move in to. The hotels then need to organise a park and ride scheme between themselves or as suggested, buy up some space for local parking although that might prove very expensive.
Well that's a quick idea, anyone else?!
