I thought the shirts were only "okay" certainly nothing special -- they were free (hypothetically, at least) so they are fine. However, these would never replace a really good souvenir shirt, in my opinion -- they really is no reference to Mickey Mouse, cruise ships, etc. -- it says Disney Sea University -- but, you really have to read it to get the idea. And the quality of the cotton was flimsy in comparison to the regualr souvenir tee-shirts -- you also pay the price for those!
