We are elite plus and use the laundry service. For underwear, PJ's, and inexpensive polo shirts no problem. We hand wash swim suits. For any good clothing, we send out for dry cleaning. My DH has good shorts, shirts and slacks as do I, and we prefer dry cleaning- Clothes come back pressed nicely.
We have a misc fund when we cruise for dry cleaning. We typically bring good items to dry clean, unless we spill something on them, or want to wear another day. I really like pressed clothes. Don't enjoy looking like a sack of wrinkles- and yes, I do bring downy spray to reduce some wrinkles.
