This is a myth that other companies don’t give great customer service. Usually have had BETTER customer service at non Disney hotels.
Recently stayed at Hyatt house across from Universal week of Christmas. Short story version: minor mess up with room category, fixed the next day, manager was able to add an extra day we wanted (remember extremely busy week ), and discounted the stay. Total stay ended up being same price for 4 days plus we had drinks at the bar two separate nights charged to room, as the original 3 night stay. Plus no peeling wallpaper, outdated outlets falling out of wall, dust in corners of room- all of which we’ve experienced at Disney resorts. In 2015 stayed pre Reno beach club room where wall paper was literally coming in strips off wall, carpet worn and frayed. Same trip stayed in Royal Pacific pre Reno room that was in perfect condition (in fact we wondered why the resort was due for Reno as it wasn’t in great shape!)
But the worst at Disney resorts is the luggage delivery- if you arrive after 5 pm forget getting luggage before midnight
. Oh and no call to tell you that BS has the bags but they stop delivering at midnight if they get behind- and the condescending attitude when you show up asking YET AGAIN where bags are
