The way you handle this year will be the trend setter for years to come.

Plan YOUR day the way YOU want it and if they can work things into YOUR plans fine.. If not... to bad! Doing all of that is to much to do in ONE day and you will be to tired to enjoy most of it. That poor child will be wore out and I would worry too, that being so tired coming home at the end of the day could be dangerous.

You have to look out for YOUR new family FIRST! (What happens in a few years when you have a few more kids?)

When my daughter got married and started her family, she let us all know in no uncertain terms that she was doing her Christmas in her OWN home with HER family and we worked with her starting with that and here we are 20 years later and it has worked for his and ours all these years with NOT ONE problem!
