Here is a rewrite that might work with the lip-flap of the balcony scene and contain the right subtext witout being obnoxious. Try this on for size.

we used to come here for school retreat. We used to swim
to that island every day. I love the water.
...We used to lie on the sand and
let the sun dry us... and try to
guess the names of the birds
singing.

I don't know birds. I don't know anything about worlds where the creatures are pleasant-- and free. I like it here -- everything is soft and sooth.
re: making the city dirty -- I haven't seen Total Recall in a while, but I remember its dirty downtown being similar to the downtown we get in AOTC. Maybe a shot or two there will work -- given the appropriate "Trooperman" touch, of course.
