Some information that I have gleaned during my travels to the US
ALWAYS tip the barman 1st, spirits are just poured into the glass,not measured, so the more he/she likes you the further the 2 fingers get apart
For good value small group day tours, we've had excellent value from "Viator tours" in the UK and Europe, not sure if they're in the US tho.
Universal Studios and the San Diego "Sea World" did a "behind the scenes tour" well worth the extra $$
If you can wrangle the times,eat in the casino buffet's about 10am, it's a bit cheaper then and you pig out for the day,
, no buying breakfast and lunch or afternoon tea
Depending on your age, most places in the US honour senior citz (apra) discounts with our seniors card (got me free travel in Anchorage)
With the US citizens being a bit paranoid about security every time you get on a plane to go from a to b you will loose a day from your holidays
Cut all your food up using a knife and fork, then discard the knife, only eat with the fork in your right hand, otherwise you will be picked as an Ozzie or worse a Pom (true story)
What others have said, travel real light, bare minimum, you can buy 5 years supply of clothing and shoes over there, hard part is finding a suite case to buy, try walmart for that
The salad is served 1st seperatly from the main course, so eat it when it is brought to the table coz your next course won't get brought out till the salads gone ( usually shredded lettuce,diced tomatoe and croutons) I think it makes them feel good about the monster meal that is about to follow
When a meal menu says "served with chips" it means crisps NOT fries
The only place we found that had a package menu item "fish and chips" was on Fishermans wharf Sanfrancisco, but when you went back to order just a serve of chips the waitress just looked blank at me, had know idea what I wanted until I referred her back to the menu item, duh.
Stand upwind of the seals in the Bay harbour
Try the crab chowder in a sour dough bread roll, just not at "Fishermans Wharf" a bit expensive there
Walk across the Golden Gate Bridge early in the morning if there's a bit of fog about
Check out the "Mission District" in Sanfrancisco, also "China"town and the painted houses.
San Diego has a great zoo, several "theme" villages and an interesting museum complex that is about 10 individual mini museums within the complex. You could get a ticket to the lot or just pay for the ones you wanted to see.Just keep your head down, your on the flight path to the airport
Americans generally want to be liked, and have a fascination of all things Australian, yes you could probably sell them the harbour bridge, along with skippy and crocodile dundee
Generally, in public places ie; Disneyland, about 5pm, show respect at the lowering of the flag
