Early October is a busy time on the Monterey Penninsula, so we recommend booking a hotel as early as possible. The host hotel for the event will be the Embassy Suites in Seaside. We've worked with them to provide a good rate. Suites start at $229 per night and can comfortably sleep four. You can also book by calling and telling them you're at the Miatas at Laguna Seca event.
The Holiday Inn Express is right beside the Embassy Suites and is a popular alternative for smaller groups.
