This is my experience:

I  had to wait more than 1 hr outside the airport terminal for the van from the hotel. Its crowded like a microbus in ktm. You will be provided a place to sleep and food to eat, but just don't expect any quality service. Good thing is there will be all Nepali people working in the hotel. I had to share a room with Bangladeshi migrant worker who happened to come from UAE. I have been in the terminal for about 14/15 hrs in S'pore and that was terrible and had to pay about 30-40 US $ for ~4 hrs of nap in the airport. Compared to that its way better. Have a safe trip! 

By the way, they treat us like a s**t and are bunch of  manner less racist thugs!  I will avoid middle east route as far as possible!
