Southern California CityPass

I'm just wondering how to save some money on my ongoing US Kids Trip 2009. We would like to spend 5 days visiting most famous park of Souther California, i.e. Disneyland, SeaWorld, Universal Studios and San Diego Wild Animal Park. I need to buy 4 tickets to each of them, 2 for adults, 1 for 12+ old child and 1 for 6+ kid. Below you can find summary of ticket prices:

SeaWorld 3 tickets for adults (10+) 65 USD/each + 1 ticket for kid (3-9) 55 USD gives us total of 250 USD for single day admission

Universal Studios has one flat price 67 USD/each person higher than 122 cm what gives us another 268 USD for single day admission (while buying tickets in advance over the Internet, you can get dwo day admission for the same price)

San Diego Wild Animal Park 3 tickets for adults (12+) 35 USD/each and one for kid (3-11) 26 USD. That gives us 131 USD

Disneyland - I'd like to spend here at least 3 days, so need 3-day pass. Cost of such ticket is 179 USD for person 10+ and 149 USD for kid (3-9). It gives us total 686 USD (price valid only while you are buying it over the Internet). When you want to buy tickets at gate, you've to pay 3x199 USD + 169 USD = 766 USD

So above option would cost me 1335 - 1415 USD for the whole family. It's a lot of money!!!

Of course I've found better option. I can pay for all above attractions only 996 USD, so it's about 40% of saving. You have to buy Southern California CityPass that costs 259 USD/person 10+ and 219 USD for kids (3-9). This price is valid when you're buying over Internet. Gate price for such a pass is 1364 USD, so only few percent cheaper than single tickets!!!
I'll go for a pass. Definitely.
