I'd say the idea of a vacation is to de-stress and have a good time.

If games help someone do that, it sounds fine to me. Just don't bring any F2P skinner box games.

A possible reason for taking a vacation is to disconnect from your daily life. If gaming isn’t part of your daily life, isn’t playing games on vacation disconnecting?

Probably the bigger takeaway for you is that everybody’s reason for vacationing is different — not everyone has access to a cottage for example.
