Did some reading on Iceland, and it seems that travelling in a small group would be a good idea.

I'm keen on travelling to Iceland in the month of October or early November - do drop me a note if anyone is keen.

there is a tip, if you would like to get cheaper price in Iceland. go in Winter time with 4 friends so that you can split car rental and gas. make the golden circle of Iceland. download an apps called it as "be icelandic" which will point you to the place of interest; offline map.
