Usually the Baga, Calaungte beaches are crowded. If you wish to have a peaceful vacation then head to Morjim or Ashvem beach. You can check out our youtube vlog on the offbeat places in North Goa exclusive beaches. Panjim city and church. https://www.youtube.com/watch?v=MxbS_1b4boE&t=20s
Goa is not something that you can explore in just two days. But since you have planned already everything, my suggestion for you would be to stay in North Goa. Enjoy beaches, try the seafood at Souza Lobo's, hit club cubbana - a must visit in North Goa if you love partying. All the best !!
