Okay here goes:
The common conception of a honeymoon as this big, extravagant trip is based in the culture of sex before marriage. Instead of enjoying each other, they need a trip because marriage otherwise is no change from their current lifestyle. (1/2) https://twitter.com/NicheCatholic/status/1293304041599049739

While I don't think expensive honeymoons are necessarily bad, I think the focus needs to be back on the couple. They should take time rejoicing in the sacrament of marriage and focus on that over any lavish trip

To be clear, I'm all for traveling and taking a vacation, my main point is that maybe right after the wedding should be a bit quieter and not preoccupied with sightseeing.
