Hi Shoaib, This being a busy tourist season, Reasonably priced decent accommodation should cost Rs. 3000 per night for 2. Add food cost of around Rs. 700 per day/per person. Local Travel and may cost Rs. 500/- per day/per person. You may budget Rs. 2500 / 2700 per person/per night. Try GTDC accommodation, which will be little cheaper and clean. You can book online.
Road trip from which city ? If you are asking for the city tour of Goa then brother hiring car costs about 1000 INR while scooty costs 300 INR in north goa. In south goa rates are 100-200 INR high. Accomodation cost about 400-500 INR pp both in north and south goa Fooding costs maximum 500 if you are a food lover , otherwise you can save in this area. These are major expenses. Rest expenses depends on your exploring interests. For example cruise ride in Panaji about 500 pp, doodhsagar falls package is about 1500 pp. A boat ride during sunset at palolem beach is what I will recommend you , it costs 500 INR pp, but it is worth for the views you witness in that one hour. Happy journey ☺️👍
