I am assuming the question is regarding where you could stay in Sam Sand Dunes in Jaisalmer. Sam has a lot of tent stays, luxury and budget. They have cultural shows, great food and its right in the desert. You can probably take a look at the stays in Sam.
Jaisalmer Desert Camp
Desert Safari Camp
Desert Springs Resort
are a few.
Hi Nishtha, while there are many professional camps in Jaisalmer, if you are a little more adventurous and don't mind roughing it a bit, travel to Khuri village and ask for who can take you into the desert and help you in camping. Others are quite commercial but at Khuri, it'll be just you, your camel, the vast desert, the clear skies and lovely stars in the night.
Check with Dlbar Hostel & Safari near fort in city they provides great camping experience too. We had great experience in budget with them. Can DM will send you their contact number too if required Thank You See You on the Road...👌👌
