We had booked the tour including a house boat vacation through Gets Holidays Delhi and the quality of House boat is pathetic, which was dirty, no service and the food very bad.
The tour operator did not show any responsibility for giving this house boat dispite confirming to us that it is the best luxury house boat. Otherwise, the stay at Munnar and Kumaramom (At Zuri Resorts and Spa) has been excellant.
I would recommend Zuri Resorts strongly but do the booking either directly or through some other tour operator. The food quality at Munnar, Kumarakom was excellant, the ambience and the scenic beauty was breath taking.
