How much to clean your shirt?

The problem with cruising is that you have to have lots of lovely clothes as dressing for dinner can be a big part of the cruise. However if you're on a fly cruise then your luggage allowance is limited.

P&O cruises offer self service launderettes on board however Royal Caribbean do not and this is a large cause of complaint.

However when I was on board Independence of the Seas I had a peak at the laundry costs and they are not as expensive as I thought, you  wouldn't want to pay them to do all of your washing but if it is just a couple of items then it's not too bad.

Item                   Wash & Press   ($)            Dry Clean & Press ($)
Mens Jacket         -------                                   5.00
Jeans                    3.50
Shirt                     3.50                                     4.00
Tie                                                                   2.25
Trousers               4.00                                     4.50

Blouse                  4.00                                     4.50
Dress                    6.00                                     8.00
Evening dress                                                   9.50
Skirt                      4.00                                     5.00
Suit                                                                   9.00

Now some of these prices are cheaper than I pay locally for dry cleaning, and had I looked earlier I would have had my evening dress cleaned on board before going home. What do you think?
