Continental Europe sounds correct. However, reading through the web links listed below, you can find a lot of non-standard outlets everywhere. Hotels cater to tourist.
India was part of the British empire. Pakistan uses the same plug. Not all outlets are grounded in those nations. Not all outlets in our 100 year old farm house are grounded, either! : )
Just to double check, I Googled for current confirmation. ( My two years there was a while back. Ironic that I would get a call today from someone who lived in the same colony three houses down.)
This site made me wonder about the hertz, though. They give the following warning: "Remember: no matter what type of plug an outlet might accept, voltage in India is 230V 50Hz." 50 Hz is not 60 Hz.

This is the plug to which I referred:

This is a variant with ground:

The note indicates that it fits into other style outlets that have round holes and flat slots together. I did not see an illustration of it but the notes for Italy gives evidence of multi pin style plug-ins.
The multi outlet accepts type D round pins and type G flat pin plugs as well.
Are you going to be in a hotel? Batteries are the universal power source. Have you considered a battery backup power source? ( I spent 2 years in Tahiti as well but we were not in hotels and rarely had electricity so I do not recall plugging things in! Our cassette tape recorder just use C cell batteries. According to the charts, Tahiti has continental European outlets AND US two prong outlets. The memory fades and experiences differ.)

I found a site that shows the dual plug with round and flat:

UK, India and Britan are shown side by side, The double round plug is the old, universal pin configuration.
I would worry about the proper Hertz, first. Look at the listing for "Our Smallest Transformer" on the walkabout website. I mentions iPods specifically.
