One key when touring is safeguarding, whenever possible, private time and space. Plan ahead, call ahead and ask what rooms/spaces are available and what times... put it in your contract if you can, so that you can schedule in some practice WHEN POSSIBLE, which will not always be the case.
Private accommodations when possible are key. You do not always need a studio as much as a room. Work can be done on a bed or in a space the size of a yoga mat. When you don't have sound privacy - things like some mindfulness meditation, which takes no space and makes no sound! is good and then long walks... and ideally in places where some sound is possible- even if just real sighing... or FF'ing your text (making an F sound for every syllable, as that consonant requires air). Find nearby classes as well... and there are now gyms in most hotels. I used to carry a jump rope... but fitness is not the same as an actor workout that requires breath, sounding and emotional freedom/practice as well.
Find the parks nearby and schedule the walks and tell people you have an important meeting! (They don't need to know that it is with yourself and some trees and actor practice...)
but planning is key... do not rely on figuring it out when you get there...
make a strong commitment to yourself and your work as an actor LONG TERM and keep up your practice...!
the pay off will be worth it!
