Its not that - throwing out a wedding party on a cheap, doesn’t really change anything. You and your partner wanting just the two of you and the closest people to be there, and the rest doesn’t really matter - that’s the core and some sort of indications that you are with right person. The more you are wanting/needing to be there for show, the more it says about your relationship in not exactly positive way.
Don’t get me wrong - if you always pictured yourself getting to the venue on an elephant surrounded by royal guards with fireworks in the background and you can afford it - good on you, go for it.
But later in life you might realized that the most important thing was not all the extra stuff, but you and your beloved. Nothing can compensate for that.
Also people taking loans and letting their families sponsor the excessive wedding to me is a bit silly. If you can’t afford it, don’t do it like that. This money can better spent on holidays or as a down payment for your first house. Its just one night ffs 😁
