*Update* As of Friday, May 18, 2018, Sam Heughan has canceled his appearance at the LV Outlander Convention.
With the press release that Creation Entertainment would be the “official” convention for Outlander came the announcement that there would be another convention held in Las Vegas, Nevada this year. They had previously announced a convention in New Jersey.
This convention is being held July 13-15, 2018 at Bally’s Hotel & Casino. It takes place before San Diego Comic-Con (which Outlander has not announced they are participating in yet).
Cast members attending so far are Caitriona Balfe, Sam Heughan, Andrew Gower, Lotte Verbeek, and Stephen Walters.
There are a lot of different events available to attend as well as autograph and photo opportunities for purchase; however, the only tickets available right now are the Gold Packages ($629) and a Gold with an upgrade to front row ($999). More ticket options become available as time passes, and the price of packages may go up at any time. I would suggest taking a look at the New Jersey convention page to see what has become available since it was first announced.
