To what end?
The criticisms I've heard seem to be in the vein of "people can't get tickets online before they are sold out for major events." People demand Harbour Station spend part of its operating budget on making ticket buying easier, rather than using the money for promoting and attracting new events.
Why would Harbour Station change what it is doing after they were able to sell out for an Elton John show in less than a day? If Harbour Station was not selling out events because of their systems, they could do a cost benefit analysis and decide if a change were in order. Right now they are selling shows out without incurring additional system costs. They should keep doing the same until there is an economic case for changing.
