Wedding Shower

The same as other showers, just with different gifts. People typically bring items related to your honeymoon destination. General items could be luggage, toiletry bags, luggage tags, robes, gift cards to local restaurants etc. If you're going to a tropical destination people could gift things like beach hats, cover ups, or matching t-shirts.

Same as what was already said but if you already have a place picked out certain travel sites like liberty travel have honeymoon registries where people can pay towards excursions or other parts of the honeymoon as their gift.

I think this would be a really cool idea! people can give you travel themed stuff like maybe some travel pouches, some luggage tags, honeymoon lingerie, etc. to go with the theme of travel and honeymoon
