Hi, Sandi,
I'll just second the gloves idea. I usually walk in May and have never been sorry to have had them along. I bring a small pair of lambswool gloves and can't tell you the number of times they have saved me from real discomfort -- both early in the morning and during those 8 hour days of walking in the rain. There are few things more chilling than a steady cold rain, and the insulation power of wool (even when totally wet) on the hands has really helped me keep going. My walking partner used to just use an extra pair of socks as her substitute gloves, but saw some cheap lambswool gloves at Heathrow on her way home from one camino and has never regretted buying them. I know it's all about choices and pack weight, but for me those gloves are essential. I'll even be bringing them to Sevilla with me in May, though I don't expect to use them much on the Vdlp!
