One of two reactions from my experiences. 1. You explain over a long period of time (weeks/months?) that you'll be travelling and what you'll be doing. The person is able to slowly come to terms with a change in routine before it happens. You set up a "new routine" for that particular day. Curiosity is engaged, and you have a relatively painless experience. 2. All of the above, but you do it really tough, with lots of screaming and distress. Once a routine is learnt, it's really difficult to break. But you can create new routines for different environments. Preparation is generally key.
