I'm planning an award ticket for next year and after having the time of my life in Delhi and Rajasthan, I wanted to head a little further south and stop in Mumbai. The way the ticket is shaping up with availability, it looks like I'd be in Mumbai in mid to late May. As I understand, this is right at or right before the start of the monsoon season and in general might be a very unpleasant time to visit.

Any thoughts on this? Should I consider dropping Mumbai from my stops or would I be able to enjoy 3/4 days without having regrets? I was in Delhi in September, so that's my extent of knowledge for Indian weather....
