Sure the captain can marry you on this ship, but you're gonna want the reception to be somewhere else. I've seen that cockpit and there's barely enough room for three humans and a wookie. May I suggest Tatooine? Plenty of room there.
When we got engaged, my husband had one request: a Dark Side groom's cake. I couldn't let him have all the fun, so I had a Star Wars bride's cake!
Of all the times I've watched the original trilogy, I never even once considered how good R2D2 would look in a wedding veil. Who knew!?
