Is it inconsiderate or rude to post things on social media about vacations?

I've been on 4 trips this year (only one really cost me money, the others we stayed with family who provided food and a place for us to stay) and I am going on a 5 one in a couple of weeks.

I will post stuff afterwards about the fun I had and the stuff I did. I'll post picture too.

Some of my friends online are people who were in treatment with me, but most are family members. I mainly post things so that my extended family can keep in touch.

I was just wondering, do you think it's rude and not being considerate of other less fortunate people?

A lot of my friends online do the same thing. They go on extravagant vacations to the Bahamas and Disney world and will post things every hour about the stuff they are doing. I just post a small message and a few pictures all at one time. Then I am done.

I know it can be dangerous too, but I will never post anything during my trip. It's always after.
