Tacky.
Gifts should never, ever, ever, be mentioned on the invitation. Under no circumstances. If there is a registry (some guests like them- it takes some pressure off when going to a wedding of someone you don’t know too well) it should be spread by world of mouth only. And it should not include luxury items or items too far outside the traditional world of wedding registries.
The “honeymoon of our dreams” line is especially touchy. It’s in bad taste to ask anyone for something they never got (would you even dream of asking for a gift certificate from a restaurant the giver couldn’t afford to eat at?), and I’m willing to bet that plenty of guests had honeymoons that were fairly humble.
I’m even opposed to mentioning donations to charity- IMHO this is double tacky. At first it is an attempt to rub how virtuous and generous you are in everyone’s faces- if you really do care there is no need to make a public event out of it. And then it is a subtle insult (implying that I’m not quite as virtuous as them because I would buy a materialist blender while they would give all their {my?} money to starving children.) And then, you have to go out and do this all in my name? No thank you! Exceptions are made for people giving to truly deeply personal causes that all the guests agree with (let’s say a nearby natural disaster, or a disease that a loved one was recently lost to) and to the fabulously rich who have thousands of invitees and would be truly burdened by the gift load.
Anyway in this case the wedding guests probably know the couple’s situation and it isn’t rocket science to figure out that they don’t want a blender.
The price of the wedding is irrelevant. If you can’t afford your wedding, scale things down. There is nothing wrong with a cake and punch reception in the public park. There is something wrong with throwing a party for yourself and then expecting your guests to pay for it.
In short- your wedding, your responsibility. Your honeymoon, your responsibility. Don’t be tacky and make your loved ones uncomfortable by begging them for money to buy luxuries with.
