We regularly laugh at people who are apparently carrying half their home with them on a vacation. We've travelled enough over the years to have a lot of tricks up our sleeves. I've mentioned several here in the past. For example, one can take along one's oldest socks and underwear and just toss them along the way. That makes for lighter bags on the return trip.
At a certain point, most travellers also realize that nearly every item in their bags can be easily purchased at any destination. A bottle of shampoo is surely available in every place you're likely to end up. Even clothes purchased during a trip can make a nice souvenirs, so it really doesn't make sense to bring everything that one may possibly need.
When going away for the whole winter though, some other unusual items might end up being useful. I plan on bringing along our Android TV box. I love it and hopefully the Internet in Luxor is robust enough for video downloading. The plastic box itself is only the size of Tim Horton's doughnut. Additionally though, I will need its mobile drive and assorted wires. I won't have our home theatre system for audio, but I can use the tiny portable ones. Oh, they will take up a little more room too. In case the TV doesn't have RCA inputs, I'll need to pick up one of these adapters. I have a zillion wires and never the ones I need. Wait, and what about a keyboard and mouse? The kilos I'll save, in bringing only a couple of pairs of pants, will be used up on other 'necessary' items.
