I think its important for everyone to decide what’s important to them.
I wanted to get married outdoors so I prioritized that. (Actually, I wanted to get married in a small ceremony in a shul in Venice, but was totally struck down by that LOL).
We didn’t have flower centerpieces at all – they are a total waste of money. But we did make sure to have beautiful flowers for me, my bridesmaids and the chupah (and all the men had nice bouttonnieres).
Photography was important so we had a good one.
I didn’t care at all about the band (was totally happy with a cd player LOL) but my FIL is a professional musician. Andy Statman (famous klezmer musician) even played at our wedding!
Also, don’t upgrade the food. Its not worth the cost. Simple is perfect.
