We just were on the Wonder on Feb 1st of this year, we had 2 rooms between the 5 of us. 2 adults in one room and in the adjoining room 3 kids. All the KTTW cards were set up to charge to only 1 room. Now using the KTTW cards to get into the rooms, guest services gave us a spare key to each room because they were not able to rekey the main card because due to legal reasons they had to have one adult in each room even though minors were in the adjoining room. Hope that was not to confussing, but having 2 rooms was just awesome instead of getting a Family Cat 4 room, was even less expensive.
