Rest time of a couple of days is good. I'm not talking about that.

But more than a week and you'll typically need to deload to avoid DOMS. More than a few weeks and it will start taking significant time to work back up, and a lot of injuries happens because people try to rush that recovery and add even more time to that.

If you regularly lose weeks at higher age, it quickly becomes tricky to avoid tipping over into lasting decline.

Depends on the goal. If staying at a certain number is the goal yes, climbing two weeks back up will possibly take more and more time. If staying energetic and healthy is the goal the number becomes only one of the moving benchmarks.

With that said I think doing some kind of workout even on vacation is important.
