Allepey is the best place I have ever visited in my life. Yes I have been an avid traveler & have traveled almost all parts of India.The place & other things are good but the travel operators can really charge you hefty while selling Kerala packages to you.
Two players I have found most reliable are Thomas Cook & Antilog Vacations. Antilog Vacations is the cheapest when it comes to Kerala.I got a 5 day Kerala package for 8000 bucks with 3 star hotels & a personal car & chauffeur. Houseboat was charged for around 3000 per person with all meals.You just can’t miss allepey guys , its awesome
