Maybe being away and having quiet evenings means that you’ll have the opportunity to put things into compartments in your mind and help you break thoughts down into more manageable chunks.
One thing I’d say about hotel.. if you’re in the hotel on your own (ie not with work colleagues) then try and push yourself to go to the bar for your dinner rather than in your room. Take a newspaper so you don’t feel uncomfortable. But try not to lock yourself in with room service. Just hearing others around you (with no pressure to interact) will ultimately be more relaxing than cooped up in the room
