About goa one thing I can say is we can enjoy all day. There many beaches to visit. The important ones are baga, candolin, vagator, sinkorien. And a place name chapora fort is awesome. Book a hotel near baga beach since it is a middle of all beaches. Girlfriend allowed in hotel but have to show id card. Liquor are very cheap so you can drink day long. Foods are very tasty in hotel but costly too. Book your hotel in go ibibo even I booked using that. 3 days enough to cover major places in goa so plan accordingly. If you want to go pub you can choose sinz pub which famous and only allowed for couples. I am writing this review after experiencng everything by myself. You can get a rentel bike to rome around goa, 250rs per day charge and you have to produce only id proof to opt a bike. Hope this help who wants to visit goa. For first time visiters goa feels like a heaven. We see people in goa always in party mood 24/7.
