Lol, Etiquette Snob here (comes with my past career), so let me address the two items that would beconsidered by many to be Etiquette Faux Pas in your posting.
Bridal Showers – They are NEVER hosted by the Guest of Honour (GOH) … but always by someone who wants the Shower the GOH (in this case the Bride) with Good Wishes & Gifts. So typically someone in the Wedding Party, or a Relative will host this event for the Bride.
What the Bride can host, is a Bridal Luncheon for her Bridesmaids, in the weeks before the Wedding itself. A time to shower your Girls with Thanks for being there to support you on your Big Day. A great time to present their Bridesmaids Gifts (items that you’ve selected for each of them indiviually… so no mass all-the-same gift… and nothing that you expect to use / wear at the Wedding… the Gifts should be personal and representative of each woman, and her own interests). Which shows how much you know her, love her, and are happy she is a valued friend in your life.
Wedding Gifts – No mention on your Invites / or Invite Package in any way shape or form. Not even the phrase “No Gifts Please”… even if that is your wish. Gifts are not an expected element of a Wedding… they are just a pleasant side-effect. Technically as a Bride you shouldn’t be talking about them at all (in olden days it was the Family Members who figured out what the Newlyweds would need, and spread the word). And so its been for eons… so if you are Registered somewhere you can let your family / Wedding Party know where, so they can point Guests in the right direction.
In modern days, things have relaxed a wee bit on this “can’t tell” front, in that if you do have a Wedding Website, it is now acceptable to put up on there some extra info for your Guests… things like Travel Info, Directions to the Church & Venue, and a quick (one line) reference to where you are Registered. “We are registered at Macy’s”… but that it is, don’t go into details, or it seriously can look like you are being Gift Grabby (more concerned with what you’ll get, than the Wedding itself and the opportunity to see friends & family there). The long time appropriate reply when a Bride is asked “What can we get you ?”… “Honest your being there is the only Gift we wish for”
Which brings us to the Wedding Reception itself. It is OK to have a Card Box (in some form / design) so that your Guests can leave their Cards & Best Wishes. It is also ok to have a table or designated place for Guests to leave Wrapped Presents if they brought them with them. In which case, you’ll want someone available to keep an eye on things (sad as it is… theft from Weddings is common).
Which is WHY the correct etiquette (as a Guest) really is to send Gifts ahead to the Bride before the Wedding… so do think about the address you put on things for your RSVPs cause that is most likely where things will be sent (an important consideration if you don’t want the FedEx guy to leave your valuables on the sidewalk in front of your house when you are not home !!)
Also, from an Etiquette perspective, the couple should not be using their Wedding Presents PRIOR to actually being married… because God Forbid if the Wedding was to not come off for whatever reason, the gifts should be returned to the Giver, so they can be refunded for them by the store where they made the purchase.
As the other Bees have said, Money Dances are considered an Ethnic or Regional Custom (as are Cash Bars)… so if they are the norm in your area, then certainly go ahead and have one.
BUT any form of “fundraising” at a Wedding that isn’t based on Ethniticiy can be seen as being tacky… most notably these Honeymoon Jars that have been popping up on Pinterest lately. As others have said, they look like “charity case” jars, so a form of begging for money… not cool. Particularly so in light of the fact that those Guests who will have wanted to contribute to your Wedding with a Gift, will have already done so BEFORE arriving at the Party to Celebrate your Marriage.
Hope that helps,
PS… Nothing wrong with having a Honeymoon Jar at home tho, where you or your Fiance can drop in your loose change, and see the amount grow in the time leading up to your Wedding. A great way to encourage saving for something that you both will LOVE so much when the time comes.
