No there are not. They do have a special about 4 days into the cruise for a discount on a bag of laundry that is picked up from the stateroom. I think it was $25 for everything you could fit in the bag.
We just reached Platinum level with NCL and that is one of our new perks (we get that complimentary) so I will definitely try it out on our upcoming Med cruise. We sail out of Barcelona on the 2nd of October.
We are flying into Paris for a few days before heading to Barcelona so we leave in less than three weeks. I am getting very excited!
