I'm not certain what you mean by favor boxes for OOT guest, but if you mean a box or a bag for an OOT that is just a little thank you to them for traveling all this way for your wedding. I'm doing them and am included snacks, water, nice shower gel and body lotion from bath and body, gum and a few other things. Just little things to make their stay nicer and their trip home more enjoyable.
If your guest are staying for a longer period of time or perhaps have never been to NY or long island some people like to include tourists attractions and things like that for them.
