As a student of BITS, Goa I would like to say :
Yes, if you are travelling person, here in Goa, transportation is not good. If you are hiring a bike, it will cost you 300 per day and for a cab, again 1200 per day.
Hostels are better than IIT Mumbai, No idea about BITS Hydrabad, but far far better than any other colleges with provision of single occupancy.
Of course, weather is quite good except the month between March to May(Too hot) after that it is summer vacation. So no need to worry.
Culture wise, I can surely say that it is better than Pilani as well as Hydrabad (No offence). Waves is one of the best fest in India after INDIGO (IIT Mumbai) No one wants to miss it.
Auditorium in Goa campus is biggest among all the campuses in India. Campus is located on a slop with beautiful view and goes down to the river. Also, there’s a lake right outside the campus.
