Choirfarm,
I get what you are saying about the CM's and I understand what the other posters are saying, but...
it might depend on how many are listed on the cards for each room. This will depend on how you or the CM set up the rooms at the time you made the reservation.
1) If your card and DH's card, each read... 2 Adults, 3 Children, you are all set.
2) If the key cards list 1 Adult, 2 kids, on one card and 1 Adult & 1 Child on the other card, you could have a problem.
I had one CM tell me, "The credits are yours to use in any way you like." I had another CM tell me, "You absolutely will NOT be allowed to swipe off more than the numbers on the card, in any one transaction."
So, if the cards are set up as in example #2 (above)... and 1 Adult has 2 children with him/her, but the card list 1 child, he/she might not be allowed to swipe off 2 children's meals.
Whew! Hope that makes sense.
I would call and find out how the room reservation is set up... or call the resort itself, as you get closer to your check-in date.
