I have no problem and am happy with giving gifts, GC or cash for a wedding or shower gifts... helping a couple get the necessity and some nicer things, or cash or gift cards for them to buy what the need to start their new life together...
For us a honeymoon is not a necessity, while it is nice, and most people strive to have one even if it only for a night or two that's up to the new couple to figure out... that's just how we feel and its our choice and money...
We have gotten some unusual request for gifts before... one couple requested gift cards ( Target,
Walmart and Local grocery store) as they were moving to a new city to start their new life when they returned from their honeymoon... Another couple that had been living together for around 8 years, requested items for camping and the outdoors and items for their camper... which is what they are into...
I never saw a couple get so excited about a double sleeping bag...or a new portable grill... I even made them some fun pillow cases for the camper for a shower gift,
I looked at it as stocking their home on wheels... One couple asked for a donations be made to the American Cancer Society.
