Chocogoingcuckoo you've not been back to tell us how you are feeling. I do hope you are not shocked that quite a few of us think trying to get married and go on honeymoon with kids would be difficult.
I should say that one thing that strikes me is that a wedding is largely something you can totally control, you can pick the date, control when invites go out and when replies need to be back by, you can book the honeymoon and have quite a free reign where and when you go etc etc. With adoption almost nothing is under your control. You have the control to say yes or no, of course, but aside from that you are waiting for social workers to arrange the home study, to have meetings, for an approval panel date, then you are reading information on children who are waiting, you are asking questions and awaiting replies and when a match is identified you are still waiting for a panel date and for intros etc!
You do not mention if you already have kids or if your wedding will be a small or large affair. If you are already accommodating children in your holidays plans then accommodating new children is not so much of an issue (except if they do not like what your existing kids like, and remember if they have come through the care system they are unlikely to have been abroad or on an aeroplane or perhaps even to a hotel ever before!). Also if the wedding is a big affair with speeches, toasts etc how will you feel if you miss a special speech or toast because you had to take a small child to the look and no one else could because your new son or daughter only trusted you to go to the loo with them?
Anyway, just thinking aloud because my wedding day was very special to me, very much about me and my dh, about our parents and other guests and having to worry about additional children can be hard I would imagine. For people who marry after their birth kids come along, as my sister did, it was relatively easy. My mum looked after the boys at the hotel and we all (me and dh and my mum) took the kids home and looked after them while my dear sis had her lovely honeymoon. That would not be possible with adopted children, or at least not for many years I would imagine.
Hope these views do not disappoint you, they are only my views as a mum to a birth dd and an adopted ds. My dd has been away and stayed at my sisters on occasion but my son would probably not feel comfortable doing so for quite some time.
Will pm you.
