A couple of the Six Flags theme parks have their own days of free admission for U.S. service members. Six Flags Great Escape in Lake George, N.Y., offers one free ticket per active duty military member during "Heroes" week from Aug. 10-14.
Then, in September at Six Flags Over Georgia, military personnel can get in free on selected days depending on the branch they belong to. The day for Air Force members is Sept. 19, when the park is open from 10 a.m. to 8 p.m. For the Navy and Coast Guard, it's Sept. 20, when the park hours are 10:30 a.m. to 7 p.m. Army personnel get their turn on Sept. 26, when the park is open from 10 a.m. to 8 p.m. Marine day is Sept. 27, when park hours are 10:30 a.m. to 7 p.m.
At Disney theme parks, each active or retired service member may receive a complimentary five-day "Disney's Armed Forces Salute" ticket with Park Hopper and Water Park Fun & More options. The ticket, which is valid for five days, admits military members to the four Walt Disney World theme parks and also allows a total of five visits to a Disney water park, DisneyQuest Indoor Interactive Theme Park or certain other attractions.
Active or retired military personnel may also make a one-time purchase of up to five five-day "Disney's Armed Forces Salute Companion" tickets for $99 per ticket, plus tax, for family members or friends. These tickets allow entrance to one theme park per day. Tickets purchased for family members and friends do not include either the Park Hopper or Water Park Fun & More options, but can be upgraded to add either option, or both, for an additional $25, plus tax, per option.
All tickets and options at Disney's theme parks are nontransferable and must be used by Dec. 23, 2009.
