Hey gaurav, I'll be happy to answer your travel queries from my experience 😊.
*goa is a great place to explore if you love beaches , forests, parties, chilling,food and relaxation. it's just a perfect place for a part animal .and the vintage vibe it gives is just unimaginable.
*if you are some party types ,north goa is preferable to you and if you are visiting goa for relaxation or isolation from busy schedule, south goa will be on your list . *since you want to enjoy 3 day trip to goa at just 4000-5000 ,it will require a low budget hotel ,or most preferably if you are solo , book your place in zostel or any such travellers hostel,at a very minimal cost .
*if you haven't booked anything yet,I would like to suggest you some things,I just checked online and found that there are some great travel deals for Goa available at tripoto itself 😊,do check this link https://www.tripoto.com/goa/tour-packages HAPPY TRAVELLING 💗
