The itineraries and activities certainly are appealing.
At first I was ready to agree the prices were high. But then I realized that they didn't include airfare. Now I think they're absurd. For the Oahu-Hawaii tour it's $10K for a family of four (plus airfare) for 6 days. That means I can spend $1000 per day and still save enough for a 7-day cruise. Even in Hawaii $1000 a day can buy a very nice vacation, thank you!
Clearly Disney is marketing toward those for whom price is not an issue. I hope they are successful, but I'm afraid I can't help them out here.
A couple years ago I participated in a survey where they offered a hypothetical Hawaiian adventure that was even more ambitious than the one currenltly offered and cost $14K. So they have actually trimmed it back a little.
