Make sure of the itinerary, cost, and what’s included and excluded in the package of the trip price. Talking about the Restricted area permit sharing, the recent forbidden areas that have been
opened for foreign trekkers. Is declared as a Restricted Area, like Upper Mustang, Upper and Lower Dolpo, Limi, and Humla Valley. Includes Upper Manaslu and Tsum Valley, where trekkers require a special permit to enter this Restricted area.
Where the cost of special permits is much higher than normal trekking routes. The Government has made the rules to maintain the eco-systems, limiting the mass flow of trekkers. The permits cannot be shared as the cost of each permit is for individual trekkers. However, when trekking around a restricted area
minimum number of 2-3 people is required.   

B: Non-restricted or normal permit sharing:

Non-restricted or normal trekking permit sharing, all trekkers visiting the Himalayas for a day or week and more. Must obtain a trekking permit called TIMS (Trekking Information Management System) in most Himalayan destinations around Nepal. In some areas like Everest, entry permits are issued by the Khumbu
village community. Whereas for the other regions, the TIMS is issued by TAAN (Trekking Agent Association of Nepal). The cost of the trekking permits depends upon the duration and areas of trekking. There is no group sharing basis on trekking permits, where each trekker needs trekking permits of their own.
As per the passport details and areas of trekking, all the permits are obtained by the local agents in Kathmandu. Also in Pokhara city only, for the Western Himalayan Region, all trekkers must join with Government Registered Company.
On booking with the local trekking agencies, they will issue the required permit for each client of the group.

Once booked with the local trekking agency in Kathmandu or Pokhara, the company will provide a guide. Who knows and has experience in the areas of trekking? Either a single traveler or more than 6 to 10 people in the group will share the same guide. Sometimes with larger groups of more than ten pax, the
company also provides a backup and second guide. 
The guide-sharing basis is provided by all the local companies for a single or more members in the group. The wages and facilities for the guide will be borne by the company once booked. The only extra that one can offer to the guide is gratitude or tipping at the end of the trek or tour. Which is not compulsory, but it is a tradition that has been practiced for many decades. When the foreigners visited Nepal and still practiced in Nepal and most Asian countries as an extra perk and gratitude.

B, Porter sharing:

Similarly, like the guide, the company on booking the trip of your choice will provide a strong and healthy porter. The guide normally picks the porters either from Kathmandu or on the way before starting the treks. The porter is required are required for trekking only, then on tours. The porter wages and extra benefits are taken care of by the company on booking the trips.
The porters also are medically insured by the related company, providing good wages as the norm of PAC (Porters Act Clause).

The lodges are simple and basic, where single rooms will not be available. Sometimes the clients have to spend overnights in a dormitory or share with 2 or more people in a big room. Having separate beds for each traveler, but
