Do they charge using only the sponsor's room key for the DDP? Second, my friend is leaving a day early and there will be two TS credits left, can i use that to make reservations for dinner show for myself? Never been to this and always wanted to go
DDP credits are pooled by reservation and AFAIK DDP charging privileges can be put on as many (or as few) KTTW cards as the group gets. So, assuming you and your friend are booked under the same reservation, just ask to have DDP charging privileges put on both of your KTTW cards when you check in. That way when your friend leaves you won't have to worry about remembering which card is the one with DDP charging privileges. And if there will be 2 TS credits left at the end you certainly can use those for a 2 TS meal for yourself.
