In fairness to freediverdude it is a sunk cost - for all of those PMP graduates following at home.

I work with many a Project Manager in my line of work --- let me tell you, they ARE special .... but I digress.
I guess we all have a different opinion.
In that same regard let's look at another sunk cost; the hotels could potentially begin charging guests to use the ferry that takes guests to the various parks (I'm guessing CityWalk

).
If anyone argued the point, "charging someone to use a ferry from the hotel is (to use my favorite word) 'gouging'", one could simply turn around and say --- "no it's not actually", since the hotel pays for:
- boat maintenance
- boat licencing and registration
- people to operate/captain the boat
- fuel
- insurance
- security
And if anyone complains, I guess one could always say, "well you don't HAVE to take the boat - you could walk right? Why would one expect this service to be free? Why make all hotel guests pay for the ferry when only some use it? PBH guests certainly use this service more than HRH -- why am I paying for it?" & "If you don't like to pay for use of the ferry, don't stay at the hotel, or at the very least, don't use the ferry then."
Anyway -- everyone clearly has a different take on this. I see it as gouging (for reasons already stated), while others see it as reasonable (again for reasons already stated) -- tomato .... toemato (if you catch my meaning).
