Thanks for the info.
I checked the itinerary for the Betanzos to Tui bus and came up with this .
City Arrives Leaves Days
LA CORUÑA/A CORUÑA 12:15 12:15
SANTIAGO COMPOSTELA 13:15 13:15
PONTEVEDRA 14:00 14:00
VIGO 14:30 14:30
PORRIÑO 14:35 14:35
It would appear that the bus calls at SDC en route,but where would you catch it? The bus station,or somewhere else?
