What happens in Vegas ... well does not quite stay there. Multiple puns intended. If you are going on a vacation with the Griswolds, anything can happen. Like Randy Quaid popping in for some unknown reason - apart from the script and probably the audience demanding it. The beloved and hated cousin is back again.

And this time it seems like father Griswold does everything he can to ruin or rather bankrupt the whole familly. Will he succeed? A fair question one might have. The whole thing is quite insane and while you do not have to have seen any other vacation movie you can see that none of the member changes ... well physically/casting wise the son and daughter combo do change. You get new ones playing them in every movie. But mindset wise ... well they stay the same - same goes for Mom and Dad - but they are being played by the same people.

If you did like the other movies, you will have fun with this too - some interesting cameos included (not sure why currently the pics used for Sigfried and Roy are ... anything but good looking ... anyway).
