Aside from the current 4 day deal and the prices charged by Shades and your MWR/ITT, I suggest checking the prices at ALL MWR/ITT locations. Many prices are listed on the base websites. The Navy will require you to call the base office. When I did my research a year ago, I found that you don't have to be in person to buy the tickets. They will send them through the mail for a flat fee. Also, at that time, Ft Eustis in Newport News, Va had the cheapest prices.
