OP here. Thanks for all the responses!
Just to clarify some things:
*
The card would ONLY go into my bridal shower invitation (being distributed by my mom) and it would explain that in lieu of a traditional gift registry, we are doing this - and of course, it's totally optional. IMO, people prefer to have registries or ideas for gifts because they either have no idea what to buy (and like me, don't want to get you something useless) or they don't wish to give cash in a card. This gives people an option still.
*We can 100% afford the honeymoon on our own, so it's not a matter of not being able to afford it.
I personally don't find it tacky, but the mixed reviews on here confirm my suspicions
that it's very controversial, which is the sole reason I'm asking.
I hear of them more and more lately, so I was inquiring if it's become more widely accepted. But evidently not, so I am re-considering.
I also think it is a generational thing, and
my generation tends to be more tolerant of it - young professionals, established in life and home, getting married a bit later in life (I'll be 31 when we tie the knot). My generation also sees different kinds of weddings and don't necessarily follow the traditions and customs of yesteryear. In fact, we are getting married in a ski village with just our parents, and having a BBQ party at a picnic shelter in a park as our reception. Very non-traditional wedding.
I do appreciate all the responses and don't mean to sound defensive, but I don't need my finances and morals questioned on the subject. Just want to know what would run through your mind if you got a bridal shower invitation with this included as a gift option as opposed to the standard registry.
Thanks all!
