From my calculations you spent £5.5k?
Did you feel you underspent, or could have saved any money in certain areas? Just trying to get a feel of budget.
I think you could have done it cheaper, for example we left it quite late for the flights whereas others have got much cheaper by getting the tickets months in advance.
I think the hotels we stayed at were of a good standard, my wife did a lot of research to get good, clean hotels with wifi and breakfast.
The hotel in San Fran was of a good standard in the middle of the centre but because we were there for five days we wanted a nicer place to relax in.
Soending money we didn't scrimp, my wife spent $200 in the Disney shop and got a lot more Sophia, we basically had around $130 a day to live on. We used the credit card a couple of times at the end, two nice meals and I bought a Google Nexus.
Hope that helps. I don't think it would have been enjoyable constantly cash counting and cheaping out on meals etc, we pretty much had a paid lunch and tea every day, we never made our own sandwiches or anything.
