No end of people need a tripod for the occasional landscape or group shot, but never want to carry their big studio model with them. They sometimes try to get a tiny travel tripod to attach to their camera bag but are horrified when they see the weight and size equation that this creates.
Overseas travel needs this equation to be solved with very small figures - but that means that the price goes up. That is inescapable - and if you add a further requirement of large lenses or camera bodies you need to go even further up the price scale. Eventually it becomes cheaper to just import the landscape rather than buy the tripod that you need to go photograph it...
If you are only going to be in the city, state, or country and plan to drive your car to the shoot, think about having a really cheap and light tripod in the boot of the car. It will be best suited to mirror-less cameras and it will not have carbon fibre or super complicated head but it will be there when you need it. If your wife drops a bag of superphosphate on it you'll only be out 50 bucks.
We've got good, cheap Promaster Vectra Delux tripods in store right now for $ 50. Flip-lock legs, central rising column, three-way video head and even a little quick-release plate. You can afford it and you might just need it.
Something for the weekend, Sir?
