Be prepared for the different cultural experiences you will have along the way!
All accommodation on our trek to Everest Base Camp is in small tea houses, run by the local Sherpa people.  You will have a bed to sleep in (albeit not the most comfortable bed in the world, but a bed to say the least), in a twin-shared room.  There are options for showers lower down on the trail, if you decide to use them, however, many people keep clean by using baby wipes and a bowl of warm water each day.  The toilet situations can be difficult at times, some of the tea do not have Western-style toilets, rather just a hole in the ground instead of a toilet bowl. Be prepared for the different cultural experiences you will have along the way!
