Normally, we travel light-- for example, once we spent two weeks in Europe with carry-on luggage alone, including bike helmets.
I had hoped it would be the same thing for our trip home, seeing as how we're traveling via Europe, with about ten billion stops along the way. But alas, we have managed to accumulate even more stuff than we came here with, which is even more incredible when you realize we have jettisoned nearly everything we arrived with and acquired all new stuff while we were here.
As a result, we've spent the morning madly weighing our numerous bags and checking airline websites to make sure we're within the limits. As with our reservations, I can't get a definitive answer so I'm about ready to give up and just pray for the best.
