As with the original GLBT Disney gathering in Orlando, Gay Days at Anaheim is not an official Disney event - the park remains open to all throughout the weekend, and GLBT attendees typically wear red shirts to indicate their participation. Events over the three days kick off on Friday, and throughout the three-day weekend, you can pick up the latest information on the event by visiting the Gay Days Info Center in the Trillium Room at the Grand California Hotel.
There are plenty of activities throughout the weekend, from the opening Wonderland Party to the Plunge (Sunday) and Kingdom (Saturday) parties to comedy performances, cocktail receptions, and lots more. Check the official Gay Days at Anaheim calendar for details.
Also be sure to check out the page on Host Hotels - these include the Grand California Hotel & Spa, Disneyland Hotel, and Disney's Paradise Pier. The Anabella and the Howard Johnson Anaheim are also sponsors of Gay Days at Anaheim.
Additionally, numerous gay bars as well as gay-popular restaurants, hotels, and shops have special events and parties throughout Anaheim Gay Days weekend. Check local gay papers, such as the Blade, for details. Also check out the excellent travel site produced by the Anaheim/Orange County Visitor & Convention Bureau.
