Here's an article about a TIA study based on 5,000 respondents that makes the following point:
"leisure travelers decide where they want to go and for how long before they even consider the price tag"
I guess sometimes it just takes 5,000 people and a few thousand dollars to tell us what we already know. Once people move along a path from "needing" something to "wanting" it, price becomes less important. And, leisure travel is all about what we want, and more importantly, how we want to feel.
