On Dream and Fantasy it is in the D lounge at various times but usually around 11 or so, late afternoon around 4:00 and evening around 7 or so. *** Disclaimer...please note, this is from my personal experience on the Dream and Fantasy **** Final Jackpot Bingo is played in the Buena Vista theater and is the culmination of the entire cruise bingos running over into one final game. Usually worth thousands depending on how many people played during the cruise. They register players and you pay for the games (and what package you want to purchase) 15 minutes before the actual game is played. For the final game, it is 30 minutes before the game begins.
I would allow at least an hour for total time between registering and playing to plan for nursery time.
It is a lot of fun and they allow the kids to play to as long as there is an adult there to authorize and collect the winnings (if any) on their KTTWC.
Have a good time.
