Default [Q] Multiplayer game without network connection

my girlfriend and i are going on vacation and we want to play so games there. We can not use our data plan there. So the alternative is, that one phone opens and Wifi network to play multiplayer/Coop games.A bluetooth based multiplayer game would be good too. I know there are a lot of lists of multi player games for android, but the most of them need a connection to the official servers for match making. Do you have any recommendations? We both have an S5, so the hardware should not be a problem. Tank you.
