Announced, Dates, Venue, City oni-con.net “Oni Con 2027 / October 1st - 3rd 2027 / Houston Marriott Westchase / 2900 Briarpark Dr / Houston, TX 77042” Separate text blocks on the homepage, joined with slashes; the "O" of "Oni" is the logo graphic. The Hilton Galveston Island Resort hotel block is no longer shown; "Book Your Hotel Room" now links to a Marriott group reservation. Galveston-era text survives only in the page's hidden embedded data.
Announced, Venue, City facebook.com/onicon.official/posts/pfbid0ZqPHkbTtX4Q4rSCA3qcnTVCDad1ZXhfZWM9tSuPAWhvQdeza6qwRQTJeMwz3Y628l “Want to book your room for Oni-Con 2027 early? Our room block at The Houston Marriott Westchase is open! … When you stay on site the fun never ends!” Dated organizer post tagged "Official Oni-Con is at Houston Marriott Westchase. ... Houston". It settles the city against the Early-Bird Registration cart linked from oni-con.net (onicon23.reg-it.org), which still reads "Oct 1st-3rd, 2027 Galveston, TX".
"Last checked" is when a maintainer compared this listing with the official site. Quotes are copied from the organizer's pages on that day.
