Yes, we have used the service twice during our 7 night stay at GC in January.
We took DS (7) over the Pinocchios the second day we got there and let them show him around and get a feel for the place. Luckily, Barbara who gave him the tour was also going to be there the night we had ressies for. We had him there for 2 hours (so we could eat at NR) and came back to get him. He ate their for only $5. He did not want to go with us and asked to stay another hour. So, DH and I went through DTD. He liked it so much he wanted to go back the next night too so DH and I spent a nice three hours by ourselves in DL.
The staff was great, they had a storyteller one night and a musician come in and entertain the other night. We plan on utilzing the workshop a few evenings again on our next trip in January.
