Closing the loop on some of the pre-charter questions I had. As far as cash - I took much more than I needed. For 5 people (where I paid for everything) I spent close to $1000 in cash. That was, frankly, going out of my way to spend cash. VERY FEW places would not take my visa/MC. Also - for fuel on a 45' Lagoon with the genset running full time and under power at least half the time, I used 92 gallons ($360).
