Using them, no advantage, but as SLP87 said, it is a great way to force yourself to save for a Disney trip. I will be going to DL in August and have been cashing out all my rewards programs for either Disney GCs or Disney Dollars, if available. If not, I try to cash out for virtual Visa and then use that to buy GCs or DDs. That way I know I will have spending money for the days we are in DL/DCA/DTD.
