Kodaikanal is an exquisitely charming hill-station and anyone travelling there can be sure to have a great time, if they’re just mindful of a few little things.
A Don’t trust ANY of the guides or agents, they’re just there to lighten your purse.
They’ll lie about anything to convince you into taking rooms probably double the actual rent, for their own commissions. Go directly to hotels and refuse to negotiate anything with them.
B. Even if you plan on a sightseeing trip with any travel agency, be careful about going with whatever’s WRITTEN on paper and definitely Take Receipts if you pay in advance. Most importantly avoid travelling with the agency called "Ayesha Travels." That agency is filled with frauds and thieves and simply cannot be trusted.
