The night before, we plan to hang out with our bridal and grooms party at the venue. Then, we have separate rooms for both. It's more to do with how early we may have to wake up to get ready (specifically the girls).
Cancel (probably). We have rented the honeymoon suite for the night before (we get it free the night of) and another room for my children. I'd much rather be comfortable sleeping beside my best friend rather than uncomfortable with teens and young adults kicking me all night. Not to mention those party animals - I'd probably end up having zero sleep.
Keeping! Because we're all (families and wedding party) going to be at a hotel the night before so it's easy to be in separate rooms. We've lived together for 6+ years so it also seems like a fun change-up to be apart right before the big day!
Sleeping at my maid of honors place and getting ready with my bridal party with fruits and champagne will be awesome. The photographer will get great pictures of me and the girls and the same on my fiance side. Will be nice to see this after the wedding.
