Best Stay in Sand Dunes at Jaisalmer + Travel & Late-Night Train Advice

Hi everyone, I’m planning a trip to Jaisalmer and need some help picking the best sand dunes experience. Between Sam Sand Dunes, Khuri, or any other suggestions, which one do you recommend for a great stay? I’m looking for something with cultural performances, camel safaris, and a good food. Also, I’d love advice on how to get to the dunes from the main city. What’s the most comfortable and reliable option? Additionally, I have a late-night train at 2:00 AM from Jaisalmer while returning. Is it safe to travel back to the city at night? Will it be easy to find cabs or autos at that time? Would really appreciate your experiences, tips, and recommendations. Thanks a ton!
