I couldn't disagree more. I believe there is very much of a market for luxury resorts in the destination theme park game. Disney has over 3,000 rooms that NEVER cost less than $500/night. And based on amenities, even The Grand Floridian is barely above a 3 star. As a matter of fact, the last year Mobil Travel rated it it was only a 3 star. A true 5 star in the $500/$550 ballpark that has around 300 rooms would slay!
and for those that say a 5 Star can't be built on that plot because of nearby hotels and highway noise. Manhattan has 104 5 star hotels each with limited space and city noise.
