Hye Jack, For budget stay you may search for the hostels or zostels in Goa. And if you are thinking to travel Goa on bike or scooty ( Rs800-1000 per day on rent) which would be a better option. Then there is no need to book costly hotels near Calangute beach. You can book cheap hotels atleast 5-10 Km far from crowded area. Hope this would help you.
