Head to Southern California this September for some deals. Book the 3 day park hopper ticket for Disneyland Resorts by September 1 and use it before September 30. If you do book it...it will be upgraded to a 5 day ticket for free, according to one website I read. Great for Labor Day traveling.
If you are in San Diego...stop and say "hi" to Shamu. Sea World's new Dolphin Show "Blue Horizons" is supposed to be great. Kids tickets are $5 with a paying adult.
Check out these places...San Diego Wild Animal Park, San Diego Zoo, Legoland, U.S.S. Midway...buying your tickets in advance saves you some money as well.
