Hello Warren! Since you are staying at the Wilderness Lodge, I would recommend you make dinner reservations at the
Whispering Canyon. I just checked are there are reservations still available for that night. Whispering Canyon is a fun and rowdy restaurant and I think it would be a great way to kick off your vacation.
Later, you can head to the water and watch the Electrical Water Pageant which is scheduled to go by the Wilderness Lodge at 9:35 p.m. (weather permitting). You'll also be able to see some of the Holiday Wishes that are scheduled to launch at 10:00 p.m.
Of course, depending on whether or not you have enough tickets (you could always add another day for a few dollars) there is always the option to head over to Magic Kingdom to view the magic first hand. But I know my kids would be just as happy doing the above and maybe taking the boat over to the Contemporary to ride the monorail.
Have a wonderful vacation! I hope you have many happy memories from this vacation! Diane
