The recognition came first. The capacity didn't follow. When NeurIPS 2026 awarded complimentary registration to its top reviewers, then opened venue booking in batches, SACs first, ACs second, reviewers last, the predictable result was a Paris venue that filled before many of those reviewers could even log in. One top reviewer, who posted about the experience publicly, arrived at the registration page to find no Paris option available. They weren't too late. They were simply in the wrong queue.
This isn't a minor logistical hiccup. It's a signal that the conference's growth has outpaced its infrastructure for honoring the people who make peer review credible. Top reviewers are not incidental to NeurIPS; they are the reason the program has rigor. When a system awards them a benefit and then structures access so that benefit evaporates before they can claim it, the message is clear: the logistics of scale matter more than the gesture of gratitude. It echoes a pattern we've seen in other fast-growing tech events. At From first users to lasting momentum: Disrupt 2026 leaders share the path forward, leaders discussed how early momentum can turn brittle if you don't build the right on-ramps for your most committed participants. The same principle applies here.
The practical consequence for researchers and reviewers is straightforward: if you are a top reviewer next year, do not assume the complimentary registration will guarantee you a spot at your preferred venue. Plan for the possibility that the perk is symbolic before it is functional. For conference organizers, the takeaway is harder to ignore. Batch-based registration that prioritizes roles by hierarchy may be efficient, but it creates a de facto two-tier system where the most publicly celebrated contributors, the top reviewers, are also the ones with the least choice. That contradiction undermines the very recognition the award is meant to convey.
We are not arguing that NeurIPS intended to slight anyone. But intention does not erase outcome. When a top reviewer asks whether Paris was "already full by the time registration opened for reviewers," the honest answer appears to be yes. That is a detail worth watching. If next year's registration process does not change, the question will no longer be whether reviewers got shut out of a venue. It will be whether the award itself still means what it says.
