We were doing the same! At one point I just looked around the room and said to my FI, "How are we getting all of this shit to Mexico??" It was a little overwhelming. We have all of these tumblers for welcome bags, vases for centerpieces, etc. We each get one checked bag for free, and then plan on bringing one extra. Then we'll have a carry-on, and I'll bring my dress on the plane. Not only getting everything into the 3 suitcases, but then keeing them under 50 lbs. is another struggle. Hopefully we'll be able to make it work. Otherwise I'll just ask my mom or siblings to take stuff, but I'd like to avoid that and keep all our stuff together. The good news is (which I keep telling myself) that packing to come home will be super easy!
