I’m going to answer my personal opinions based on each one of your ideas, I don’t mean to offend so please don’t take it that way!
I myself had considered going with a christmas wedding [a white & blue frost-bitten wedding!], but decided against it since travel in our area is HORRID during winter. We went with halloween instead [although, NOT halloween themed].
* Gingerbread House as cardbox or centerpiece
This would very much depend on what the gingerbread house looked like.. you could be treading very dangerously close to kids christmas party instead of elegant wedding! There are card boxes that are made from metal that look like presents, I think this would help bring in the elegance but keep the christmas theme.
* Maybe have a family style dinner/holiday feast?
Great idea! We had actually considered this – we were discussing a large ham & turkey dinner with all the fixins’ just like christmas! Do keep in mind cost, though – catering a large hot meal like this could take alot of work to DIY and cost a buttload around christmas. For our 80 person wedding we were talking we’d need about 8 turkeys, which we could cook ahead of time, debone & heat up the day of. But that’s still alot of work with over wedding woes! The ONLY downside to this could be that your guests eat a bit too much like christmas.. and are sluggish/tire afterwards!
* Twinkling lights
Yes! Who doesn’t love those!
* Christmas tree instad of gift table , guests could put the gifts under the tree
Could totally be a great idea, I picture are very large tree with lots of room for presents underneath – my only concern would be if you were having any children at the wedding, they might be inclined to play with the gifts! And, if no table, where would you set the card box?
* Have some Christmas cookies, eggnog and hot chocolate and spiced wine for the guests.
This could be a great idea for a late night snack!
snowglobes as favours
I can tell you that I don’t personally own a snowglobe, nor would I want one… I think they’d be a rather expensive favor and most of your guests wouldn’t want/keep them. I would highly suggest going with an edible favor, or even a candy buffet [in christmas colors? to die for!]
mistletoe in the center of the dance floor
photos of everyone with Santa?
This seems to be going a little overboard to me.. again, venturing into kids party instead of wedding. If you are interested in something like this, perhaps you could do a photo booth, and have santa/elf/christmas props!
Ask everyone to wrap any gift they may be bringing in christmas wrapping?
This would be cute, but I wouldn’t worry too much about it. I’ve found that most of the time guests tend to wrap presents in wedding paper.. which is usually silver or white – which would totally fit into the christmas theme.
* Apple cider, candy cane and hot cocoa favors (the cute ones in jars with cocoa mix, marshmallows and cin. sticks)
Once again I feel like this would be a waste of money… i mean hot cocoa is great! But, most of us have tons of it at home if we like it.. and I wouldn’t have any use for the little jar it comes in. Candy canes are alright – not sure how many people really like them though or if they mainly consumed by children.
personalized ornaments (in mini Christmas stockings)
I wouldn’t take these home.. all of my ornaments match on my tree at home, and I change them yearly.
cranberries/pine/”snow”/ornaments in tall vases as centerpieces.
This could be really cute, I’ve seen lovely centerpieces using ornaments, pine, cranberries, poinsetta – it all just depends how you bring everything together!
Card box that looks like a chimney
Same as the gingerbread house.
* Christmas tree somewhere in the room, and in your invitations, ask guests, via a cute poem or note or something, to bring you both an ornament, and once they arrive, hang it on the tree so that your first Christmas as a married couple, your tree will be filled with ornaments from your loved ones.
I would do this.. but I wouldn’t ask your guests to bring an ornament – your guests really shouldn’t be asked to bring anything specific! But, if you really wanted the ornaments, you could use the tree just as you planned, and get plain ornaments, and have guests write messages on the ornaments and hang them up! If you are inviting kids, you could have a color-your-own ornament station using either handmade ornaments or the clay ones – they can use paint pens to color!
* Music: For cocktail hour and for dinner, have some Christmas carols. Hire some Christmas carolers to stop at each table and sing carols. Ask one of your friends to dress up as Santa and distribute some beautiful gifts to the children in the wed.
I think christmas music for cocktail hour & dinner would be very cute – I wouldn’t do the carols though. I certainly wouldn’t want people singing at me when I’m trying to stuff my face of turkey! I really don’t like the idea of santa being at a wedding, it cheapens it for me – like.. we were at a mall or something. And the gifts given to the children in the wedding should really not be given to them with everyone else around.. it could make other children upset/left out.
* I love this idea of having your guests write love notes and advice on Christmas ornaments and hanging them on a tree!
