I live in Los Angles. I'd like to give you some advices if you want to save your time and money.

Day2
Enjoy Las Vegas in the evening and night but not in day-time. This place is lively in night but looks boring and nothing to see in daytime.

Day3
Fly to San Diego so that you can spend more time there. It's very very good city to tourists. Starting from old town, then take a old-town trolly. you get to see coralado harbour (you'll see aircraft carriers), San Diego downtown, carolado island and Bolboa park. you can get off along the way and take next trolly. It comes every 30 mins. It'll take your whole day if you enjoy it.

Day 5
You can omit the wild animal park if you want to save a day. it doesn't have much to see as you thought.

Day 7
Why spend another half day in disneyland. your time is precious and half day won't give more fun that you already have in day 6. just go to universal studio directly. it's a very fun place. if you have time, you can go to sunset blvd after you get out universal studio. i've live in LA more than one year and I only went there once.And I did find the street of fame. sunset blvd is ugly you'd like only have a short stop there.
