I love tourneys but they don't make sense for this situation. People will be upset when they bust out and have to wait around. People want to play poker not watch others play poker, especial for noobs who may make ill advised calls or bets and get felted early. Set the limit low enough so that 3 rebuys is still under the limit of uncomfortable losses. I was exclusively a tournament player for a very long time going back to the days were most of the tournaments were limit tournaments at foxwoods, so I naturally tried to get the family to play tournament poker, well they hated it. They want action, and they want it from the first hand dealt to the last so a cash game it is. Now with my friend group, we only play tournaments, but these are seasoned vets who understand poker. I would rather play a tournament than a cash game but I know that for the family game it usually doesn't work out. I'm sure there are family games where people play tourneys so I know its not impossible but I think for a new group the cash game is a safer bet. Blinds stay the same, they can come and go as they please, and they can play all night if they choose.
