Howdy,
Just got back from a long two week trip which included 3 days in orlando and a week at VB.
We used both Cash, AMEX TC and CC's. Most of the stuff went on our CC's, as we have a very good tendency to pay them off. Cash was used for most incidentals and places that didn't take CC's.
This trip I chose to take TC's over an ATM card. A single ATM transaction fee would have cost more than our TC's, and to be honest, I'd rather AMEX get the money for the TC's than pay usurous fees that ATM's now have.
You can cash TC's at the VB and BW main desks without a purchase. Just don't expect to do $1000.00 at a time, as they don't have tons of currency on hand.
Hope this helps,
Joe
