We've used it three times and will use it again in Sept. No negative reviews here. But then again, we never tried to maximize it by figuring where we could get the most for our money. We ate where we wanted. Nor did we try to stretch our credits by sharing, or paying OOP for dd so we could save her credit. We just used it how it was supposed to be used. It was never a hassle for us, servers were wonderful and always very helpful explaining things. We always came out ahead by using the DDP and ate at some wonderful places.
If we try to stretch, share or pay OOP it will be due to having booked a 2TS meal. Have you done that?
