Adding a person to our room reservation
"My daughters and I are planning a week vacation to WDW in October. We are spending 6 nights at POP Century. My sister lives in FL and wants to come up and visit the two last days at the parks with us. I was wondering if I could add her on the last two nights at POP. I booked the vacation online.
All or Nothing
That sounds interesting. Have "auntie" swoop in for a couple of days of fun and frivolity. That's pretty cool.
As to adding her to the reservation for a partial visit, it can't be done. Disney's computers aren't set up to add someone for part of a reservation. It's an all or nothing deal.
"Sneak Her In"
That being said, Disney doesn't monitor who's actually in the rooms once you check in. You could always just sneak "auntie" in. Just don't tell Disney.
Dad's Bottom Line
It's not all bad news. You can't add "auntie" to the reservation, but you can let her stay in the room for a couple of nights.
