Goa is a good option.
But just sharing a point of concern. It is extremely important to be
careful in selecting Hotels in Goa for International Conferences .There are
many Hotels violating many coastal regulation zones and environmental laws
.
2 years back Tehelka Think Fest faced a similar trouble .
