Yeah watching a movie is solid but i try to save that for the end game... and try to choose a pretty bad funny movie so she doesnt get to entrenched in that, so you can still get kino and keep her focused on you, not the movie... then i introduce a little wine if possible so she has an excuse not to go home, cant drive, been drinking...
oh well you will just have to stay here then... hahabut if shes at your home in the early days its too easy to go for too much too soon so i avoid that.
the cheapest outside the home that works is just take her for coffee or a milkshake or something... then go for a walk, sit at a park or something if the weather is nice or take her to the mall if it is too cold for that.
just follow her around while she looks at clothes and what not...
