Guest Relations has tripled it's responsibilities since last January. RFID tickets, MagicBands, Park Entry, MyDisneyExperience, FastPass+, Service Centers, Regional Kiosks, DAS Cards, MemoryMaker, Credit Card Guarantees for all Restaurants, and more. It's a perfect storm of policy changes and intangible issues with technology that is operationally unstable. Couple that with the fact that their existing faculties were not expanded and that they are relying on iPads with lackluster applications, they are struggling on even the slowest days. There are no quick fixes.
You then have Cast Members and managers who are reluctant to change with the times to learn these new things. They haven't seen a significant raise based on the responsibilities they have taken on. They've also tripled the number of Cast Members on hand. These brand new Cast who don't have the level of training to effectively or efficiently solve challenges.
Then factor all of the negative things that have taken place this year... poor planning for most Limited Time Magic events, Annual Passholders not getting plastic cards, FP+ limited to resorts, then only same day FP+ for most, Downtown Disney, Candlelight changes, Frozen characters, and Monorail downtimes. Then the normal declining of degrees and standards slipping while the prices increase. Add in an ever growing population of non-domestic and non-English speaking clientele with very different cultural backgrounds too.
I hope this answers your question.
