Of course, it's a complete guess, but does that seem likely to anyone else?
Maybe. There are some counterbalancing forces that might discourage travel and/or change the nature of it at least for some people. Economic activity has been hurt tangibly. I keep hearing a variant of "Only waitstaff and bartenders (and other poor people) lost their jobs and they don't travel anyway" but I don't think you can partition the economy that way. (I am also angry about the implied "well those people don't really count" sentiment, but that's another topic for another board.)
The pandemic is going to change some habits, at least in the medium term. M is not sure when she is going to feel comfortable in a dense crowd; she was our biggest DCL fan, and she currently has no interest in ever going on a cruise again, even post-vaccine. She's also not sure she ever needs to be in a theme park---and frankly, neither am I. Will that change someday? Probably, but not right away, and maybe not for a good long while. So, there may be some pent-up travel demand, but the trips people take might look very different.
Some travel isn't going to be dependent on how people feel, but on how governments react. I suspect a US Passport will be functionally useless a lot longer than most people think, and who knows when Hawaii will change its quarantine policies. Kauai had something like 110 licensed acute care beds on the entire island as of 2018. The population is only about 72K, but they have between 100K-130K arrivals each month in a "normal" year. They don't have a lot of room for error.
There is also a lot of grief right now for a whole host of reasons, some having nothing to do with the pandemic. I don't know about you, but that's reoriented my sense of what is important and how I want to spend my time. For example I care much less about sports these days, particularly college athletics. I was already quite disillusioned about the latter even before the pandemic, but this past year has thrown that into even sharper focus. Likewise, I'm not currently in the mood for escapist entertainment (as might be represented by WDW) because I can't escape this inner feeling of sadness and loss. I'd much rather sit on a mountainside and be in the healing presence of nature.
Business travel may take *much* longer to recover---and it might never. Many businesses have discovered that the things they think had to be done in-person really don't have to be anymore.
I know for us, our 2021 travel is completely speculative and may or may not happen. We have fewer things planned. More are drive-to/low-key destinations. Few will be in crowded destinations, and those will be almost entirely outdoors. None will have an international component. Most are much less expensive than typical. Disney is not a part of it. All of this is a change.
