You should talk it to your partner and explain it cause not everyone could understand you as an investor, for you it might be not so big but for others it is a very special moment for their life.
If both of you couldn't seem to agree on each other on this one then might as well consider how you would live after marrying each other?
You need to see a partner than wkuld understand you and you also needs to understand your partner.
Sometimes it is not just about the money it is also the moment and memory that you would create, that is why there are people who are spending so much money to make those memory special.
