Is there anything I can do to add a little color to my skin tone?

My husband and I are going on a cruise in December this year. My skin is almost as white as a sheet. I would like to get a slight tan so I would not look so pale in my black dress. I don't want to go to a tanning booth, because of the cancer scare. I have had a melanoma on my upper arm about 10 years ago. I have thought about the spay on tanning but don't know how well it would work or how long it would last. The cruise that I will be going on in a 10 night. Any suggestions will be appreciated. Thanks!
