Well I'm a guy, but this is the first I have ever heard of the moon cup. Going to recommend it to some friends as an alternative to the usual remedies. Seems more environmentally friendly.

@CCgirl83, you might consider taking Dr. Bonners liquid soap with you. It can be used for many things (just about every type of soap need) including shaving if you feel the need to use something. A little goes a long ways. Machka's suggestion for just prepping with warm water and a washcloth is good though. I even do that shaving my face quite often.
