We've done the CP Pkg twice now, and we're doing it again on Dec 6. I think its a great deal, especially if you're going to be eating dinner at a World Showcase restaurant anyway!
Dinner includes an appetizer, entree and dessert (the last two years, it did include soft drinks - I'm not sure for this year). Also, you get a 15% discount on most purchases made that day in Epcot. (We usually do most of our shopping on that day!) Then, you get good seating for the show - and it cuts down on the amount of time you have to wait to get in! Last 2 yrs, we've walked up about 15 or 20 minutes before the show starts and pretty much walked right in, and got great seats!
We're doing an early dinner at France, then the 8:15 show. The show will let out in time to get a spot for Illuminations!!
