If you add an extra zero to most of those budgets you'd just about have ours (though not as much as Aussiemum).
It sort of went like this:
"Let's go for a week to the Gold Coast" (Australian holiday area, like a small scale Florida).
"Hey, for almost the same price Qantas has a special deal to
Disneyland"
"Ok, let's go to Disneyland for a week instead.
"But if we go all that way, we can't just see Disneyland"
"Ok, let's make it 2 weeks, and we can see San Francisco, Vegas, Yosemite and the Grand Canyon as well"
"What about Seaworld in San Diego, and the Zoo, they're very close to Disneyland?"
"Ok, let's make it 2.5 weeks"
"My friend in Seattle says we have to see her if we go to the states, and you have a cousin there too"
"ok, let's make it 3 weeks"
So, 3 weeks, and about $US20,000 later we've been to Disneyland! (and never regretted a cent of it, it was the best holiday of our lives)
