Going to India

I'm lucky enough to be invited to go to India for my friend's wedding: Akash and Anu from Stanford are getting married in Trivandrum, which is in Kerala in South India.
To forestall the obvious question - no, it's not an arranged marriage, they've known each other since college, they are both American, but they have a lot of family still in India so it's a lot easier to have wedding there than to fly all the relatives to the States.
Why am I going? Well, if anybody ever invites you to an authentic wedding in an authentic India, the answer is always "Yes!".

Naturally, a ton of people from San Francisco are coming, including my roommate, so it should be a blast.

The wedding festivities are supposed to take a few days, after which all the "americans" are going on a 5-day tour of Kerala. After that I'm taking another week to travel to Mumbai, Jaipur, Agra (Taj Mahal) and Delhi.
