we've done it twice before and will do it again. no fit issues, just sent in measurements. quality was typical of a decent rental. DH got like 3 wears out of the tux/pants, didn't need to bring along any formal wear office own. we have an upcoming 7 night, so he and the DS will do this and we can get some nice pictures and stuff. the tux arrives in a bag, i think they have up until 6 or something? ours wasn't there before sail away, we were a little nervous in case something needed to be switched? it seems like there is a magical rental room somewhere onboard that they disburse the suits from and i think have maybe a couple extras of things to change out if needed? anyways, ours wasn't in the room and we were a bit worried but it was to us by the end of dinner - or the end of the show before dinner i think. i wouldn't 100% assume that it would be there for a formal dinner the first night, but overall so easy. i think it comes with 2 shirts as well. he just got the basic tux situation. we were very happy!
