at 13 months i doubt your LO would lose interest in weaning after a long weekend. but, you would likely be engorged/uncomfortable and risk blocked ducts/mastitis if you don't pump during your trip. i would try to pump once per day, at minimum.
here are some old threads on the subject that might be useful:

We haven't done a full weekend but we went away for a night. I think DS was about 18 months or so. He was fine but wanted boob as soon as he saw me. I did not bring a pump and regretted it. My higher producing boob was rock hard and I woke up and had to hand express in the middle of the night and again in the AM. I don't think weaning is a forgone conclusion but it will be fine no matter what. Have a great trip!
