I still have a KTTW card with 7 days still on it from a trip I took on business 3years ago. I want to book a 2 night package w/dining and 1 day ticket for DH and 2 kids (We also have left over parkhopper tickets w/1 water park day left). They said everyone in the room has to have the dining and ticket package. (This makes me really upset that I paid all that money to upgrade that ticket back then). If my husband just books a room package him and my to boys, is anyone gonna notice if I show up later that night to stay in the room?
Everyone staying in the room should be registered with the resort. That's pretty much a standard requirement thoughout the hotel industry.
Aside from the fact that registering with the front desk is the right thing to so, if you are not registered in the room, you will not have a room key. That means no EMH for you since the room key is used to identify you as a Disney resort guest who is entitled to it. Your old room key will not be valid.
If you're staying at a resort that checks room keys at the pool, you will have no identification to show that you are a guest at the hotel.
You will not be able to have the dining plan because as far as Disney knows, you are not staying at one of their resorts on a package.
If you want the dining plan, you will have to book a package with tickets. The only exceptions would be military families staying on a room only discount with dining added, AP holders staying on an AP discount room plus dining package and DVC owners/guests staying on points.
You can book a dining package with as few as 1 day on your tickets (except during
free dining when you have to have 2 day passes). If you get everyone 1-day passes, you can upgrade your husband's and sons' tickets to more days. You can either save your own 1-day ticket for another time or use it during that trip.
