0.8 meters in the hotel corridor is ok.

When hotels and restaurants are evacuated, the clear width of walkways should be calculated and determined according to the prescribed evacuation width index. The minimum clear width of stairs and walkways in hotels and restaurants with multi-storey civil buildings should not be less than1.1.2m. For hotels and restaurants with high-rise civil buildings, the minimum clear width of stairs should not be less than1.2m..

At least three people walk side by side, so it won't be crowded, because you have to consider safety issues such as fire fighting. If there is an accident, it will not be embarrassing to evacuate.
