We stayed in TTDC Kodaikanal for 2 days in family cottage room, it is OK, but tap water is very very bad. Water is fully yellowish color. I dont know about other hotels in kodaikanal. Might be whole kodaikanal water supply is like this only. Due to scarcity of water to kodai. .
Due to this we scared of taking food from TTDC restaurant. We used to take food from outside hotel.
IMO totally kodaikanal is very very costly in all aspect.
