As a pp said, it depends on the kennels, and the dog, some dogs won't cope in kennels.
Don't just take the nearest or first kennels. I've looked at a few kennels that I wouldn't put my dog into. Nothing wrong with them particularly, they just didn't feel right for my dog.
I found a lovely family run kennels some time ago when I needed to have my dog looked after.
She doesn't go there often but she seems really happy there, and when I pick her up she always goes back to say another goodbye before we leave.
It's out in the country, lots of lovely running areas, three runs a day and they have a special section for small and/or nervous dogs, also with their own running areas.
I have looked at home boarding but most of the people I've seen seem to have dogs of their own, which my dog would hate. I wouldn't want someone moving into my home and I wouldn't use one of the companies that pair up dog owners and boarders.
I think your DH is being silly. I was very nervous before my dog first went into kennels but I needed somewhere for her to stay, not for a holiday, and it worked out fine.
Either you find somewhere you're both happy with or you're never going to be able to leave your dog. And as pp said, within reason, the younger the dog is the better the chance of them accepting the situation.
