More serious response:
I use Money to handle records on ALL expenses.  It connects to my bank
and to all my credit card accounts and downloads the info.  Once a
particular type of transaction is identified to a category and
sub-category, similar transactions are automatically identified.  For a
trip I set up a new category for that trip and then all transactions (or
at least all possible) are either on a credit card, debit card, or gas
credit card.  When all the charges have cleared and been down loaded
there will be a few minutes of making sure each transaction is in the
right category such as "2003 Grand Canyon Trip, sub: Gasoline".  I can
then generate a report that gives me a breakdown on gasoline, camping
fees, lodging fees, food (eating out or groceries), etc.
