If that were me (I should be so lucky - only get to caravan in UK) I would be making sure I had sufficient strips and lancets (if you're doing testing) to last the time, or oral meds or whatever, as a priority. Then I'd add the famous carb counter book so I could eat out a bit. And if I were on insulin, I would be having medical details (translated into Portuguese) somewhere on my person so I could be rescued if something happened. Others will have other suggestions! Have fun anyway.
