They also have a "bag special" during the week. It's all you can fit into a plastic bag (size similar to a tote bag with drawstring). It's $25 and you can stuff lots of underwear, t-shirts, shorts into it. It's wash and fold only so anything prone to wrinkles is not going to yield the results you want. We use Downey Wrinkle so shorts and t's are fine. We do this on every cruise. LOVE IT!!! We've also had to have a white shirts laundered and pressed> We only pack one for the 2 formal nights because it's only worn a couple of hours. Unfortunately, there was a spill, but the price is really reasonable.
We always have DH suit dry cleaned for $9 the first day, saves on packing because it is in a bag in our carry on. We also send his 2 clean formal shirts, different colors, just for pressing @ $1.75 (half price) and always get everything back for the first formal night.
