In case of Bali flight is the main challenge. Because there no direct flights from India. So the flight prices are high compared to other South East Asia destinations. I don't know your leaving city so that I can guide you better about the flight. Rest things you can cover within 5-6 days so your travel cost will be less. visa is free for Indian citizens. Your budget is slightly tight for all travel costs. So better you increase your budget upto 45k per person that will be better I think.
Hi Deepali, Bali is quite far from India, so you flight costs will be quite high. Other things like hotel, food, local transportation, sightseeing depends on how much you wanna squeeze in. I suggest you do Phuket if the budget isn't too high. There are direct flights from Delhi and Mumbai, so it helps save costs.
