The question is really difficult. First of all, it's not usual to have a holiday before the wedding. People prefer to have some rest right after the ceremony. For instance, I had a wedding in an interesting place
https://www.poptop.uk.com/venue/nancarrow-farm/ and only after all ended (restaurants, ceremonies, meetings with relatives, friends, and so on) we finally visited Miami. But anyways, I think your wishes should be respected and such a behaviour isn't good. I would let my significant other have some time with her family.
