Any cost to add 1 person to AP ressie for a total of 2 adults 1 child?

[tinkerbellmagic]

I am going to book a room for 1 child and 1 adult. If I twist the arm of DD18 and get her to go with us again, is there a charge to add her to an existing AP room ressie well before the 6 days out deadline?

Also, would the existing AP ressie stay in place with her added or would CRO cancel the first ressie and make a new ressie, thus taking the chance of losing the original AP room/rate?

Thanks for any help,

You may add an second adult --no charge. Third adult is $25 more per night, and no your reservation will not change. Just call CRO and add the name of second adult.

Thanks a bunch! That's a relief.
