I apologize for not responding to answered post. It never entered my mind.
I am overwhlemed by so much to learn before taking my first cruise that I have been spending all my time just reading and reading.
In the future I will respond to those answering my questions.
We're doing this for our cruise. In fact, a lot of us from our meet group are getting matching tee-shirts. My fiance got them for us, so I don't know where he went or what he did, but I'll see if he can post some links for places online. I think he looked online, but then ended up getting them at a regular "brick and mortar" store where he lives, but I'll have him post what he knows on the subject here.
3) If you do get it printed locally, make sure you set a clear expectation on when you'd like to pick it up. Wouldn't it be awful if the t-shirt printer was closed on the day before you leave town to get married. It's a good thing I will have a day or two when i get back before our cruise.
Why order, I just made 9 for my family. By t-shirts you want, find a magnet design you like, personalize it, put on transfer, and iron on. This was the first time I did it, and the turned out great. Hope this helps.
These were our matching shirts (YDD had a dress that she wore w/ black leggings) for the Christmas Cruise in 2010:
These were the matching shirts we wore to MNSSHP last Halloween (again, YDD's was a dress):
We had these for our All Girls Cruise:
We've done other things as well, but those were just shirts that I bought from the Disney Store that all matched.
HTHs!
