it all boils down to all's comfort level.
if you going to do things that your friends like, for example
arcade, and your gf will be there like a vase, then allow your gf
to do something more meaningful and meet you later lor.
if your gf is those who is very sporty and fun, then all can join
in and have fun.
end of day, all should be happy. If not, then better tailor.
