The count the organiser prints
The CANVAS home page carries two figures. It prints "3000+ Abstracts" and "4,000+ scientific innovators". The meeting runs four days at the Oregon Convention Center in Portland.
Three thousand abstracts across four days works out to 750 a day on the organiser count. The programme index sits behind registration, so the per-day split is not public.
Five nights around four days
The venue books Halls A1-B-C from Friday 30 October to Wednesday 4 November. That is a five-night hold around a four-day meeting.
Two workshops run on Saturday 31 October. A presentation workshop runs 2 to 5 p.m., and the first half of a two-day Bayesian course runs 3 to 5 p.m. The second half runs Sunday from 9 a.m. to 4 p.m.
The Sunday 1 November workshop block runs from 8 a.m. to 5 p.m. A delegate on a Saturday workshop holds the Friday night. A delegate on a Sunday workshop holds the Saturday night.
Tuesday carries two workshops, from 1:30 to 4:30 p.m. and from 2 to 4 p.m., inside the meeting window.
Thursday 5 November sits outside the hall booking. The venue November calendar lists nine events, and the next one opens on 6 November in Portland Ballroom 251-252-253-258.
The daytime window
Sunday 1 November carries workshops and no plenary programme. The building runs from 8 a.m. to 5 p.m. on workshop sessions that day.
A day-use operator sells the hours between a delegate arrival and the room release. On 1 November those hours hold a full workshop block in the same building.
The onsite registration desk keeps its own clock. It runs 4 to 7 p.m. on Saturday 31 October, 8 a.m. to 8 p.m. on Sunday, 7 a.m. to 5 p.m. on Monday and Tuesday, and 7 a.m. to 12 p.m. on Wednesday 4 November.
The registration ladder
Registration opened on 9 June and the rate table carries three windows. Through 2 October a professional member paid $715 and a nonmember paid $1,015. From 3 to 7 October the pair read $810 and $1,110. From 8 October the pair reads $910 and $1,210.
The gap between member and nonmember holds at $300 in all three windows. The member rate rose 27.3 percent across the run and the nonmember rate rose 19.2 percent.
The other rungs move inside the same windows. Emeritus and graduate student members paid $365, then $440, then $535. Early career members paid $590, $670 and $765. Undergraduate members paid $135, $165 and $195. One-day member tickets read $560, $660 and $660. Virtual-only registration costs $225 and $325.
The register page states the member line as "Society members save more than $300 on registration, $25 in abstract fees". Membership must sit on the record before registration to reach the member column.
The clocks that closed
Abstract submissions opened on 27 March. The in-person abstract deadline fell on 23 June at 4 p.m. CT, and abstracts stay editable through 4 November. The virtual abstract deadline fell on 23 September.
Cancellation terms moved with the price. A registration cancelled before 3 October drew no penalty. A $100 fee applied from 3 October, and a registration cancelled on or after 8 October draws no refund, ticketed events included.
The refund request deadline for registration fees and the tours and workshops registration deadline both fell on 23 October. An attendee who wants a workshop seat holds a registration first.
What an operator prices here
Two nights carry workshop demand ahead of the meeting: Friday 30 October and Saturday 31 October. Four meeting days follow, and the hall releases on Wednesday 4 November.
The registration desk shuts at noon on Wednesday while the meeting runs its fourth day. A delegate with a Thursday departure holds the Wednesday night.
The venue runs cashless. It takes credit and debit cards and touchless payment.
