Scd my shoulder knee and elbow? Going on a cruise soon?

I fell off my bike and scd my shoulder knee and elbow. Most of the force of the fall landed on my shoulder and the abrasion is about the size of 2 thumbs. I have a sc about the size of 1 thumb on my knee and a small sc on my elbow. I'm going on a cruise in 2 days and was wondering if I will be able to go swimming and tan? Is there anything I can do to quicken the healing?
