Even if call center staff was paid double rate of now, each person can only handle so many calls/hour. WDW needs to hire more people.
Alternatively, (joking) WDW can put me in charge of this customer service crisis. I will declare a “cross training opportunity” for middle managers to help out rank and file workers. Frame this as a chance for them to go above and beyond (if they want a shot at “exceeded expectations” at their next yearly review).
For a company as big as Disney, surely there must be quite a few well-paid email-forwarding do-nothings, working from home less than 8 hours a day, who can be mobilized to help answer questions or escalate to higher level helpdesk.
