Coorg - accommodation options are plenty. Based on your needs you should choose the best. Hallimane - is typically suited for college student groups, who are looking for a economical stay - with lots of space for partying.
Equipped with many rooms and few cottages apart from 2 dormitories it can provide accommodation for a good number.
With a group of 45 friends (29 Men+ 16 Women) I checked in to this place. The owner and manger were very adjusting and provided accommodation facilities for all of us at a reasonable rate.
Close to Kushalnagar, so if you base your Coorg trip with Tibetan Temple and Dubrae Elephant Camp on first day. This is a perfect spot for your evening accommodation.
They have a good enough pool attached which you can use. The camp-fire area is pretty big, and they will do all the needful on your demand. No restrictions on time. It would be a wise idea to carry some nice music because the collection they have is quite pathetic. Be prepared with mosquito repellents when you are partying outside.
Barring the accomodation, the food here is not so great. An ideal substitute would be to contact Kingsway Restaurant near by and ask them to arrange a bon-fire buffet dinner for you at this place. The managment of Hallimanae have no issues usualy in doing so.
The friendly staff - attended to us in all our needs. If you would like to purchase anything from the nearby town, they will do it for you anytime. I would recommend that you proceed to Hallimane atleast by 5 pm after your first days trip to make the most of the facilities here. Some time in the pool with your friends and then bon-fire, music, dance, dinner and party in the open air would be a fantastic idea.
I'm not sure how great this place would be for family and couples, but for big groups it is really one of the better options and affordable rates.
