Kindly stay in South Goa specially in palolem beach area, as it will be peaceful and not very crowded as well. If you want to enjoy night life and crowd, then only opt for north Goa as the beaches will be overly crowded and will be little chaotic. plus rent a car for exploring the city plus have a lot of anti tan cream as it will be very hot during the day time starting from 10 am till 5pm , so would suggest you to do beach hopping early in the morning, plan a day for snorkeling, which will start from Coco beach, for that you have to book in advance so that they can arrange for pick n drop, plus doodh Sagar water fall is a must with the kids so that they can have the Chennai express feeling.
You can stay near Arpora Market. The area is pretty good and is approximately equidistant from both the famous beaches of Goa (Baga & Calangute). North Goa is very commercialized, so if you want some peace you can stay in South Goa, beaches in South Goa are not at all commercialized. Also staying in North Goa will give you edge as Chapora Fort, Vagator and many good beaches are in the North.
First week of Goa will be hot and way humid.
Dehydrate your body time to time.
Avoid outing during afternoon times.
Keep watch on kids when on a beach.
If you are expecting peace then stay at south Goa, it's way serene.
Goa in April. The temperature is very hot during that time. But if you have already planned, then do head to South Goa- Its very peaceful. Cola beach and butterfly beach are best beaches. Palolem beach - Picturesque spot
You can stay Morjim, Goa. The distance from Morjim to other reknown beaches are around 16km. Moreover, Morjim is a silent location with a silent nearby beach. The best resort adjacent to the Morjim beach is Naga Resort. My stay in the resort was one of the best experiences. As per records, the best time to visit Goa is in the month of Dec, Jan and Feb. But I have visited Goa on both off season as well as on season and both the experiences remains almost the same, except the crowd and climate. So, enjoy your travel.... Goa is awesome as always....
As it would be very hot there...carry all the baby essentials which protects them from sun... carry a floater tube for them so that they can enjoy beach bathing...calangute and condolim beach are best for bathing... anjuna beach is also good ...
if possible and if time permits visit dudhsagar lake also... skip some beaches as they have same views.. also would suggest u to stay at Cabo Cabana cottage...it's a private stay...at the mandovi river bank...with beautiful views at night😍
