There are so many people coming from Mumbai. They can hire a transport to take them directly to the venue (Mahindra United World College of India, 7 kms from Paud ST bus stand). It's a long way from the city so this would save a lot of money and time. Post here if you're interested, but specify the date and time you plan to travel. And do give contact number / email (write it as johndoe[at]email.com to avoid spammers)
