When you're traveling somewhere especially for only a few days there's nothing wrong with traveling light. I made a huge mistake when I went to Montreal a few Months ago I brought a backpack with me and a huge suitcase that I had to check in. It wasn't worth it in the end because of the amount I had to pay. When you're going somewhere for only a few days you can't go wrong with bringing a Backpack and a carry on suit case. That way you're saying money and if you want to have a lot of clothing with you just make sure you fold your clothing then roll it up before you place them in your carry on or backpack.
