I visited Jaisalmer 2 years back and my experience is quite really good. Best time to visit this place is winters because its too hot there. There are many sight seeing points in Jaisalmer like Sam dunes, Gadisar lake, Longewala border and Jaisalmer fort. You can enjoy the evening in the mid of sand dunes with cultural activities and relax in cottage. You can book desert safari and ride camel there. It won't charge you a lot, the packages are pocket friendly. I would recommend you to visit this place atleast once in a lifetime.
