Precisely. I spend a substantial percentage of my income on travel, and I'm only able to do that because I'm frugal in other areas.
I've not read most of this thread, but I'll say that for me, personally, I'll travel as far as I have to if there's a park that I want to visit. I've done long weekends in very far away places - and I've always had as much time as I've wanted in the area.
