This is interesting, and really could become a lasting thing. Say you set up 10 of these in all 4 parks and charge 650 per hour, then operate them for 12 hours a day (just for this thought experiment) everyday of the year. Let's do the math:
12 Hours x 365 Days x $650 x 4 Parks x 10 rooms
= $113,880,000
Whoa.
They only need 40 really wealthy families/corporations/celebrities to book these per day, or a few more to book partial days. Do they exist? I wouldn't be surprised if they did.
Think of how cheap this would be to build and operate too. A couple well built and well themed rooms. A handful of minimum wage attendants to clean and provide service to the guests. Some snacks and drinks thrown in too. This would be almost pure profit. Margins would be extreme.
This is in the tradition of the VIP Tour guides and Club 33. Though even more starkly VIP. I can't help but have some negative feelings about this, but still it makes a ton of business sense if it works. We'll see.
