My general reaction to this is a big yawn, since most people are generally going to look at the total cost of the room and not just the base rate. Disney has always increased room rates substantially every year, and it doesn't matter to me if they break out these fees or build them into the base rate. To me, a base rate of $350 a room plus $15 for services is the same as a rate of $365 per night without the separate resort fee as long as the services are the same.
I think there would be a revolt if they tried to add these fees to stays with DVC points. It would cause some people to pull out their contracts to see if this would even be allowed.
I wonder if one of the objectives of something like this is for the company to reduce the amount it has to pay in some state or local taxes. We all see that string of room and occupancy taxes that get added on to base hotel rates at Disney and everywhere else. Maybe hotel services that are priced separately and are not directly related to occupancy of the room are not subject to those taxes.
