DH whined
incessantly about having a "just us" vacation for just the two of us, to just relax in a warm place away from our Illinois winters.
So, I explained it like this to the DGD(6): The next time we go down to Disney we're not going to go to the parks or do anything fun

- we're just going to sit on the balcony and hang out in the room.
She of course assumed I was joking, but I finally sold the concept by asking her: When we go to stores, does grandpa like to look at the fun stuff with us? And her reply was; No he likes to go look at the boring old grandpa stuff. So I asked again: And if grandpa can pick the store, what kind of store does grandpa want to go to.. and again the reply "He picks boring old grandpa stores".
You could see the light slowly come on, she finally realized I was serious, and that grandma and grandpa were going to go to disney without her, but it was kinda ok because its to be a boring old grandpa vacation, and we're not going to do any fun stuff
We will avoid the parks, but we also have a lot of sight-seeing, shop browsing, and DtD and BW activities planned.
