First, you've got to find someone who has actually paid $741 for a RIV studio. It was on sale before it even opened.
True. But with tax, $550-$650 per night has been common, even with discounts, depending on time of year.
And room rate inflation at Disney is a lot more than 2%.
So base it on a current average selling price of about $550, to be conservative.
3% per year increases are still on the conservative side for Disney.
So... after 10 years, that would be $739 per night. After 20 years, $993 per night. After 30 years, $1334. After 40 years, $1794 per night.
Granted, the future is impossible to predict. And "past inflation is not an indicator of future"
Over the past 50 years, Disney resorts have increased prices far more than 3% per year. I expect the hyper-inflation to continue because I expect demand to continue to grow faster than supply. (Disney really can't increase the capacity of their current parks by that much... Competitors are limited in their ability to offer competitive hotels as Disney controls the real estate immediately surrounding the parks).
Now..... things could go the other way, with decreased demand. Contributing factors: more global pandemics truly hurting long term international travel, theme parks could simply become less popular. Global warming could make Florida a less desirable location.
While we may see a temporary 1-2 year decline in demand, I anticipate continued demand growth.
