Earlier I posted that we have had a decent number of view upgrades. I want to say that we always arrive after midnight, so for me I do not believe that arriving late effects our room. I think reading the DIS forum you get the sense that a lot of people checking in will ask to change their room if they do not like something about it and leaving all bad rooms, but I think that it's a very small number.
Because Disney Resorts blocks most rooms several days in advance, it doesn't make much difference when you arrive. It's likely that the room you get will be exactly the same for a guest arriving at 3pm or midnight.
The same late-night arrival might play out very differently at a "normal" hotel. Most hotels assign rooms when you arrive to check-in. The later you arrive, the less choice you may have. But, it really only matters when the hotel is at high occupancy.
Happy to clarify, but I'd ultimately defer to your expertise on this, as revenue management is a science/art that is outside my field. I had been taught that, for most hotels, optimal profitability is somewhere lower than 100% occupancy, but could vary depending on situations. I tried to Google for some articles to illustrate what I mean, and here is an example of one from a vendor. But in general, a lower occupancy target (at least earlier on) allows for higher room rates and more dynamic pricing strategies. I'm totally not an expert in this area (it's more of a business curiosity), so I could be misunderstanding the model completely. It's interesting that a hotel catering to business travelers will probably have higher cancellation/no-shows, and should overbook. And perhaps that applies to WDW as well, in a way I hadn't considered.
Some of that is true. There's little point to lowering rates just to hit 100% occupancy. And I could certainly see how a small hotel owner might need a company (like the one to which you linked) to point that fact out.
But, for the most part, that's not a factor for any hotel that's part of a chain. Chain hotels generally have strict, pre-determined rate structures. As those rate structures are used to set corporate rates, they don't get changed much...if at all. (There are two types of corporate rates. One type is a locally negotiated rate. Those only apply to single hotels and are often huge discounts. The other type is a percentage off of the normal rates. Those percentage off rates are granted to companies that give the entire chain a lot of business.)
While the Revenue Manager may alter your rate structure slightly at various points throughout the year, once the rates are set, they're set. At that point, your main goal is going to be to get to 100% occupancy as often as possible. But, that's not the sole goal. You also want to use the busy nights to increase occupancy on shoulder nights. For example, every hotel in Las Vegas could sell out with people staying only Friday and Saturday nights. Through the use of stay controls, you'd work to build up occupancy on Thursday and Sunday by requiring a 3-night minimum stay.
I'm old. When I started working in revenue management, we did calculations using Excel spreadsheets. Today, it's all done by wildly complex computer software. The software using in major chains (including Disney) takes most of the decisions away from people. (Good software can analyze more in a minute than I could in a month.)
Anyway, it's true that 100% occupancy shouldn't be the ultimate goal...profitability should be. But, in practice, large chain hotels and Disney Resorts with reasonably inflexible rate structures aren't in a position to alter rates just to chase 100% occupancy. In effect, 100% occupancy is reasonably equivalent to profitability.
