This is probably unusual, but I spend some 100 nights a year in Asia, paid by my own (not other people's) money. The weakness of the euro in 2015 cost me several thousand euros extra. This occurred even though I was able to shift some of my travel from countries with poor exchange rates (e.g., HK, TW) to places with decent rates (e.g., Indonesia, Malaysia, Japan). So yes, exchange rates do have an effect on some of us, although of course you're right that, barring the most extreme swings, for the average 10 day trip to Japan the difference won't amount to more than a few hundred dollars.
