This was my third RS tour, and although I'm getting better at packing with each tour, even so there are always some things I bring that I wish I left at home. Here are the extras I brought that I could have done without:
A second pair of shoes (wear one, pack one). Could have just taken the shoes on my feet. Never used the backup pair. I know this involves a little risk (what if I step in a puddle?)
I brought a jacket, a fleece pullover, and a fleece shirt as layers; I should have just brought one or two of them, not all three.
I brought the whole RS Italy book, should have just torn out a few chapters and left the rest at home. I never want to do that to the book, but it would help with weight and bulk - that book is heavy.
I did bring an umbrella that I never used, but its small and I still think I would bring this in the future.
My suitcase is a Ravenna Rolling Case. Here's a funny thing: two people on my tour had exactly the same case, and in the same color as me!
What about you? Anything you bring that you wish you left at home?
