I think at this time it is not advisable to travel internationally 'just for fun'.
It makes much more sense to travel within your own country. As an ads campaign here reads "you are going abroad for ... you sit right next to it" where ... is a different item each time but the ones they name can be found in most countries. So find if you can find a good holiday in your own country.
Countries move from the 'do not go' list to the 'travel possible' list but also back. Requiring repatriation in some cases and going into self isolation (or worse) on return home.
International travel is possible but be sensible and only travel if you have a strong reason.
I am still planning one international trip myself but that is to meet up with my boyfriend whom I have not seen since early 2020. While I am willing to take some risks for meeting up with him, I am not willing to take those risks for going somewhere alone. And that is while I am itching to travel.
