I think you could go on the reservations web-site and bring up your adrs. There is a section that asks if you are celebrating anything and you could add that.
Maybe the easiest thing, though, is when you get there, have the Concierge at your resort add to all your adr locations.
You should also get pins when you arrive that say Just Married and if you wear those and you have an attentive server, that should get you some special attention too.
The other contributor is correct, though, in saying that some places do things and some don't. I had a notation on our Ragland Road adr that we were celebrating my son's birthday and they really didn't recognize it, but later in the week when I hadn't made a special notation on the adr at Boma, he got a birthday cupcake. Both days he was wearing his celebration pin, so it is hit and miss.
