How can we say demand to goa from SC ??
Check the buses and flights which runs daily from Hyderabad to Goa for demand.
Railways cannot start trains to each and every town from metro due to infra issues. So for these type of places best option will be brake journey. I posted regards chennai here to show that brake journey options are very easy for hyd people to down south.
FYI...
more... i never been to GOA or CAPE. So there is no point in supporting visited place.
