I'm going to be on the QM2 the same time. I looked into renting a tux, since I would be out of the country till may 5th, the cost was about $200-250. Yuck I said. I went to Burlington Coat Factory and bought a tux(jacket and pants) for $100, shoes were $40 at a discount shoe store, my tux shirt was $10, cummberbund and tie was another $10, and cufflinks and studs were another $15. so for $175 I have my very own tux and I get to keep it. it might be an idea to buy one. If you go on another cruise you'll be ahead of the game.
