Please share your recent experience. I'd really like to read about the new changes from those that have done it. (We have ADRs at Le Cellier for CP, but I'd love to hear about everyone's experience.) Thanks for your input!!!
We (and by "we", I mean "I"

) didn't realize that CP would be on during our visit until about 30 days before our trip.

So when I called, the only thing that was available was Biergarten at 4:00 pm for the 6:45 CP show that evening. We'd never tried Biergarten before but thought it would be interesting, so we took it.
I don't know if Biergarten is usually very, very, unbearably, very, tediously, very, very slow to get you in for your ADR, or whether the backup was due to the an influx of CP guests, or some other reason, but it took them quite a while to seat us. We checked in at 3:50 and our name was called around 4:35. In the meantime things backed up big-time: it seemed like 2-3 dozen people checked in and/or were waiting in a long line to get checked in, and some get very frustrated and asked for the manager. When we finally got in, the place was about half empty, so I have no idea why it took so long.
I also don't know if it's usual for Biergarten, but it seemed that there were quite long lines at both buffets. We were probably one of their first dinner customers so we didn't have a very long wait, but at the end of our dinner we noticed the 2 lines stretched back and circled around each other until you had 2 intersecting snakes of miffed guests waiting to get their food.
Speaking of the food--very, very good. Loved the Sauerbraten, the red cabbage, the potato dumplings, the bratwurst, the sauekraut and the dessert. It was fun sitting with another family, and we enjoyed the show, too. They sang some carols such as Silent Night, and it was very nice. It just seemed they were not ready for the crowd they got for dinner.
The CP was wonderful--Isabella Rosselini was fantastic, and the music and lighting were amazing. It was DW's favorite event of the entire week. We got in line for the reserved seating about 30 minutes before the show and got great seats--mid-row, about halfway back. They let in a lot of standby guests, but I couldn't tell if everyone who was waiting standby got a seat.
We also got reserved Illuminations viewing, in the Showcase Plaza area between the 2 gift shops. The area felt about 1/3 full, at most--probably because of the cold temperatures that evening (low 50s by the time Illuminations started). It was a nice little perk.
Overall, we enjoyed the CP package experience very much. 2 TS credits for Biergarten was steep (especially given their issues with managing the crowd), but it was probably our 1 time to see the CP and we wanted to make sure we saw it. We found we had too much food with the
DDP, anyway, so it wasn't a big deal for us to use 2 TS credits.
