All mine I travel for, my tattooist is an hour and a half away, the one I've been going to since 2014 and he's going to finish my body. I know that travel distance is nothing to some of you, but for someone who is prone to travel sickness, it is a lot. I always book a couple of days off either side, so if getting inked on a monday, travel on a saturday and travel back on a wednesday. By the time I am travelling back, the excess ink is all off and my body is more settled for travelling back home. The reasoning for me for resting before tattoo, is that body is rested after travelling, more relaxed, which makes for an easier tattoo session. I have got tattooed before on day of arrival and it was too much for my body. Learn what works for your body and go with it.
But yes, have a rest time after your tattoo and yes travelling, no matter the distance, means longer time getting tattooed. But you can appreciate each piece you get done, before moving onto next piece, if getting continued work by them. It also builds up a relationship with your tattooist, which is important. Also listen to your tattooist and talk to them, communication is highly important. Whether you travel or no.
