Okay, I've only been to Disney once before and I'm not as well-informed as others here, so I know I will receive good advice 
Let me see if I can explain this well. This is a complete surprise to them. So with that in mind, we are staying at Pop Century and they are staying with their two adult daughters for the week. I am planning to have them go to dinner at the California Grill and spend the night at the Contemporary that night. I have poems for that day that I have planned to place where they can see it and lets them know what is going on, without letting them know too far ahead.
My only problem is that I have the last poem that tells them they are going to stay the night there and contains the room key. I do not want to give it to them earlier because as much as I love them, I'm afraid they'll get curious and open it early, even if it says not to. I was thinking that maybe the waiter could give it to them once they are on dessert or close to finishing the meal.
I have two questions. First, I want to verify you can pay for a meal with the room key. Second, will California Grill even do that? Would I run the risk of them losing the note? I would drop it off only a few hours before the meal.
Sorry this is so long and thanks for your help.
