I have to say you guys are awesome Thanks so much for all the advice.
Going to Italy has been a dream of mine for a long time but for various reasons, other trips took priority. I remember being in Greece and then in Switzerland and feeling like I could almost touch it. Then we sort of booked the trip on a whim a few weeks ago and I almost felt like I didn't have enough time to prepare. Then I read a suggestion to travel light, with something you can carry easily and decided to go with it but then I realized I had no idea how to travel light. I'm feeling better now though.
