I always thought they should have offered different levels of immersion - from the 5k a night that they had, to something much less for a room, dinner, and just wondering around in another world. Or, have a highly themed hotel for most of the year and then have some special weeks with full immersion. Seeing how loved the experience was by most, you would think there would have been some way to save that investment.
And I would love to see what their projections were on the revenue side. How many people did they think would come up with the cash needed for a stay and how far off were the actuals. I suspect the cost side of it quickly got out of control and that caused the pulling of the plug.
