Absolutely! You should definitely have a bridal waltz/first dance – but only if you truly want one, not just because you feel obliged.
If you do, however, given the small and intimate crowd, your first dance/bridal waltz is likely to be just that little bit more intimate and special.
Your first dance as husband and wife is one of the highlights of your wedding day and will provide a lifetime’s memory for not only you and your partner, but every one of your guests as well.
Don’t miss out on this very special moment unless you absolutely do not want to do one. Either way, there is no obligation to do so. It’s just a lovely tradition.
