Kumoricon runs November 13 to 15 at the Oregon Convention Center in Portland, in Halls A-A1-B-C-D-E. The convention publishes a discount for nonprofit educational youth groups: 30 percent off the at-the-door weekend membership for ages 6 to 17, and one complimentary adult membership for every five paid youth. The application closes Saturday, October 24. The convention's hotel blocks close on Wednesday, October 21.
What 30 percent takes off
The 2026 at-the-door weekend membership is $100 for ages 13 and up and $35 for ages 6 to 12. The group rate is 30 percent below the weekend price for youth aged 6 to 17. A 13-year-old pays $70. A child aged 6 to 12 pays $24.50.
Single-day memberships carry a 20 percent group discount. At the door those are $55 on Friday, $60 on Saturday and $55 on Sunday for ages 13 and up, so a discounted Saturday is $48.
Ten youth at the weekend rate pay $700 through the programme. The same ten at the door pay $1,000. A club of six pays $420 and brings one adult free.
The group rate is calculated against the at-the-door price. A discounted youth weekend at $70 sits below the $95 Ghost Neko pre-registration tier, which is the last online price before the door.
The chaperone ratio in practice
One adult chaperone receives a complimentary membership for every five paid youth memberships. Extra chaperones pay 30 percent off the at-the-door weekend price, which is $70.
A group of 12 youth earns two free chaperones. A third chaperone costs $70 and brings the party to $910. The same 12 youth and three adults at the door cost $1,500.
Kumoricon requires at least five attending youth members, adult chaperones travelling with them, and an organisation with government, nonprofit or tax-exempt status. The discount applies to members under 18 who belong to the applying organisation. The convention lists an established record of serving youth among its requirements.
Approval is discretionary. Kumoricon names four grounds for refusal: no nonprofit, tax-exempt or government status; an unverifiable parent organisation; too few chaperones for the number of youth; and misrepresentation on the form. The page also states the convention may decline for any reason.
Four dates, in order
October 21 closes the official room blocks. October 24 closes the group application; no application is accepted after that date and no discount is applied retroactively. October 31 is the deadline for Kumoricon to send approval or denial. November 7 is the close of pre-registration, and the discounted memberships have to be bought by then.
The sequence puts the room booking ahead of the discount decision. A club that waits for approval loses the block.
That exposure is small. The official hotels take a card at booking and charge it on arrival. Kumoricon states that a change or cancellation carries no fee when it reaches the hotel at least 72 hours before check-in.
Approval arrives as a coupon code or a private registration link sent to the contact address on the application. The codes apply to the memberships and expire with pre-registration. An unfinished purchase at that point cancels the group rate.
Rooms inside half a mile
Four hotels publish Kumoricon block rates, all within 0.4 miles of the hall.
- Hyatt Regency Portland at the Oregon Convention Center, 375 NE Holladay St, 0.1 miles, $235 a night.
- DoubleTree by Hilton Hotel Portland, 1000 NE Multnomah St, 0.4 miles, $185 a night.
- Courtyard Portland Downtown/Convention Center, 435 NE Wasco St, 0.2 miles and an eight-minute walk, $214 a night.
- Hotel Eastlund, 1021 NE Grand Ave, 0.1 miles, $199 a night.
The rates exclude tax. Kumoricon prints Portland occupancy tax at 16.5 percent.
Three rooms for two nights cost $1,410 at the Hyatt and $1,110 at the DoubleTree before tax. The taxed totals are $1,642.65 and $1,293.15, a gap of $349.50 that a club controls without touching the programme.
bookMyTeam publishes its group rates against a block of 10 rooms a night and notes that some hotels discount from five rooms depending on season and availability. A three-room club sits below the usual threshold and can still put a request out. bookMyTeam lists 103,857+ hotels across 46 states.
Check-in as one party
Kumoricon requires a government-issued photo ID from every attendee, adult or youth. Each attendee under 18 needs a parent permission and release form on file, signed and handed in at check-in. An attendee under 13 needs a parent with them. Memberships for ages 5 and under are free.
The group checks in together. Kumoricon states that all members receiving the discount, with their chaperones, must attend and check in as one party, which sets the meet time before the badge desk opens.
The building runs cashless. The underground garage holds 800 spaces, opens at 6 a.m. and charges $15 for up to 18 hours with no in-and-out. On event days the entry rate runs $15 to $25, charged as you enter. Overnight parking is prohibited, and the P1 level clears 7 feet against 9 feet on P2.
What the page leaves open
Kumoricon names no cap on the number of groups it approves and no minimum room night count. The discount page carries no figure for how many applications it receives. The page describes the 30 percent as typical and states that rates and arrangements can vary case by case.
Kumoricon is produced by Altonimbus Entertainment, an Oregon nonprofit public benefit 501(c)(3) organization, and was first held in 2003.
