As for the budget, a rough estimate of:
Hotels: $150 USD a night per couple
Food: $100 USD a day per couple
Transportation will already be taken care of, so there are a few misc things like airport transfers, metro passes, etc that will be added on. As for activities, the nor cal contingent is planning $100 USD per couple per day on average. That being said, when Amber wants to buy a 500e chandelier in Paris and have it shipped for another 100e, we will need to use 8 days of activity money to offset this wonderful purchase... not that we would EVER do something like that.
