You may already be aware of this, but the Embera Indians wear VERY little clothing. This is not a problem for us, but it may make some people uncomfortable. As wapanda10 said, it is very interesting to see their lifesytle. As for restrooms, try to go at the Gatun Lock while everyone else is watching the ships move through or when you get there. When we left the Lock the ladie's room line was so long that they finally "converted" a men's room to accomodate all the women!
