Doug,
All sorts of advise on this will come - I am sure of that. One good way to approach it is to calculate what you are budgeting for yourself and then bring between 30% to 45% of that in cash and make sure your credit cards can handle the rest.

Like I said, formulas will abound - looki at them and see if you can combine thoughts and make the one that is best one for you
