Is it morally permissible for Effective Altruists to travel (far) for pleasure?

Little can be found on the ethical dilemmas we face when choosing to travel for pleasure (or doing similar leisure activities).

Travelling (far) has:
- An environmental cost, most notably greenhouse gas emissions from flights
- Opportunity costs, both time and money. Travelling is pretty expensive while many human and non-human beings/​organizations/​ are dying to get money. Time off is also limited when you’re employed. Wouldn’t it be better spent improving your skills, doing projects, learning, … ?

Travelling probably also has some benefits.

Curious to hear what EAs here think about the subject.
