Not sure what you mean. Do you mean how to people afford i?. If that is your question, the same way they afford anything expensive.
Either they charge it and worry about it later, or pay cash as they have that kind of expendable cash, or save for a certain length of time.
We have a vacation account and we have Disney Vacation Club.
Many people do make very good salaries that visit Disney. I have a friend who is 25 and she got a $500,000 bonus this year. So yes she can afford to pay cash.
