Points to Note:
We booked a 12-seater tempo-traveller for the trip who would be staying with us for the whole duration. If you are going by your own car, then it might cost you lot cheaper. You can click on the link to see the page we used to book the 'Serenity Homestay'. The booking should be made little early due to high demands.
About the weather, it is never too hot in coonoor, and from what I know temperature lies within the band of 8°C - 25°C. Although it did not rain when had gone there, but I would still suggest checking weather forecast before going there.
One point I would like to emphasize on is: one should always carry the emergency medicines, since this place is little remote and you may not get everything so easily.
So, let me know whether you liked this place or not, in the comments. If anybody has any questions about the trip, you can ask that too. I'll try to answer them ASAP.
