This is a city centre location so public transport serves the area
well - please use it! Or better still, walk!
The following Lothian Buses go to George Square:
2, 23, 27, 41, 42, 45, N27
In addition, the following Lothian Buses go to Nicolson Street, just a couple of minutes walk
from George Square:
2, 3, 3A, 5, 7, 8, 14, 29, 30, 31, X31, 33, 37, 37A, X37, 42, X47, 49, N30, N33 & N37.
So there really is no need to come by car. If you must, however, a large NCP car park is located
next to George Square, with access off Potterow, opposite the 'Human Be Inn' bar.
