You can always make a side trip to Downtown Disney and get pirate shirts there. They now have a store where you can custom make your designs.
When we went they quoted us 90 minutes. Not quite sure what I was expecting but it wasn't 90 minutes. We went back after 45 and it was ready. So if you're going to do this store, do it first and then walk around the rest of DTD.How long is the wait generally at the new shop?
