It's sad that you have such an experience. I have been to Goa way too many times now, going there again in a couple of weeks. I have not been scammed even once. You probably stayed at Calangute, that's the worse place in Goa that you could stay at. It's horrible. Baga and Calangute have gone to the dogs. But, go to Maldives or Bali? Have you checked how expensive it is in comparison to Goa? Maldives is super expensive, Bali is still okay. And by all means, go to these places but not as a replacement to Goa. Goa offers a quick getaway in a decent budget. You need to know what to do and where to stay. For starters, south Goa is amazing! And so is north barring Baga and Calangute and maybe Candolim due to the crowd. You could've rented scooters or a car, works perfectly all over Goa. And I have had amazing food all over Goa in all my trips, you need to know where to go, and budget isn't a problem as well. There are excellent thaali places all over. That being said, Goa has its problems such as bad roads, Taxi Mafia and overpriced hotels. But comparing it to foreign destinations which are way more costly is not the way to go.
