Mon. night. Coctails at 6:30, dinner at 7:30. Last time we went they had 2 seatings. You will get an invitation when you check in at arrival. One year, cocktails were at 7:30, with dinner at 8 [last April]. Sometimes, depending who you are dinning with, it can become a long eve., you might not make friends, but you can always get up. A big thing is who from the resort sits at your table. This can go both ways. Anyway, the food is always great. Gotta love it.
You also usually have someone that works at the resort at your table (managers etc). We ended up chatting with a really nice couple from Kansas City two years ago and ran into them everywhere at the resort. My hubby happened to have a business trip to KC recently and met up with them for dinner! You should definitely go - you meet some great people.
