We just returned from a 3 day vacation at DL and stayed at the GC. On Tuesday morning we were passing the entrance to CA at about 9:15 am and were able to join a "sneak peek" tour of CA for GC guests. A cast member escorted the group into the park 15 minutes before park opening and provided some inside insights about the park. We were then ushered into Soaring and allowed to have the first ride of the day. Apparently, GC doesn't publicize the "sneak peek" but it is available, at no charge, to a small group of GC guests, who have the luck or knowledge to show up early at the GC entrance to CA.
