It's great. But you have to approach it differently than a vacation. You go to a different location, find a nice place to work, and work. On your downtime you can go out and explore. But don't push it. You need to focus on mostly working. And maybe on the weekends exploring. If you do that you'll have a great time.
But I think most people try to cram in a vacation in addition to working everyday. And they hate it. Because they're overloaded. Just think of it as working from a new place for a while. And it's got some interesting things to do. It's not a vacation opportunity you need to exploit to its fullest.
This goes double e so if you're traveling to be opposite side of the world and have time zone issues. Your work has to be your priority. So maintain that time zone. And don't try to stay up at weird times. It's going to impact your enjoyment of the workday
