I would not know if anyone ever said 'never' but I certainly recall the spiel on the tram from the parking lot to the TTC where they would say stuff like 'Disney tickets never expire' and 'Disney is open 365 days a year' so I could easily see people expected that as policy, but policies change.
Again, this is actually what I was told, not that it really matters. I even recall the specific location: the Guest Services booth at the IG, and who was with me. That was before MYW tickets.
And I chuckled at the CM who said it. He didn't like that I chuckled. From there he mansplained- er Disney-splained? to us that WDW was a premium park, etc.
Since then, well, have you ever tried to upgrade a park ticket? Go to 3 different Guest Services CM's and they will almost certainly all tell you a different price. Maybe things are different now that tickets are date specific, but somehow I doubt it. In 2019, a front gate CM even told me park tickets can't be upgraded!
I can think of many times CM's have said things to me that were flat out not true. That is a big part of why I read these forums.
Another somewhat funny example I recall was. well it was almost like Abbott and Costello's baseball bit, "Who's on First." The Contemporary's main building is called the "tower." and the lake behind CR is called, "Bay Lake." The DVC next to CR is called "Bay Lake Tower." The rooms that are located in CR's main building either face towards MK, called "theme park view" or they face towards Bay Lake. On WDW's website, rooms that face towards Bay Lake are
now called either "standard view" or "lake view." But previously they were were called, "Bay Lake view." Do you see where this is going?
WDW's Club level is sometimes called club level, and sometimes called 'concierge level' even though the ground floor of CR has a 'concierge desk' that is available to every CR guest.
To matters even worse, the Contemporary also has 2 club level areas. One of CR's club levels is called the "Atrium club," even though it is located on the 12th floor. CR's other, smaller, less well-known club level is located on the 14th floor (there is no 13th floor at CR). The smaller club level is called - get this - the "Tower Club Level." The 14th floor is tiny, and is mostly large 'suites', but it has 3 rooms that are roughly standard hotel room size. Two of the rooms face Bay Lake, and 1 faces MK. All three are categorized as 'standard' view rooms.
Nowadays, most club level rooms and suites are listed on WDW's webpage, but for many years that was not the case. Previously, the only way to book CL rooms was by calling WDW, or a
very knowledgeable TA.
I once had the misfortune of calling a WDW and getting a CM that didn't know any of the above. He kept trying to tell me I didn't know what I was talking about, and kept quoting me the price of a 1 bedroom 'suite' at "Bay Lake Tower" DVC, and that the Atrium of CR is the open lobby that extended above the monorail.
In any event, the above names all terribly overlap one another. I long thought the 14th floor of CR was an internet myth, because it initially took me quite a few calls to find a CM that knew what I was calling about whenever I attempted to call WDW for pricing. Mind, I was nearly certain staying there was out of my price range, but calling was the only way to even get pricing.
CM's are people just like everyone else. most are very nice, and do the best they can. In some cases though, if they don't know an answer to a question, they just say it can't be done or doesn't exist.
The Disney Dining Plan also had all kinds of inconsistencies depending on which CM you asked. I could give examples, but this post is already too long. I've long said WDW's polices are too complicated. I fear this new band looks nice, but I know WDW. Having two types of bands is likely to be another example of WDW being too complicated for their own staff to manage.
