Trade Off - TS4 Game-play Challenge by EQCreations

Okay a few questions.. sorry if they are there and I didn't see them or unspecified and up to the player.

Can you aspiration hop? Both of my sims have a main aspiration I set for them and that's the one they have to complete in order to "win" I do enjoy hopping around though for reward points and something to do. I have already started doing this but thought it's something that should be clarified.

Can they travel alone? My played sims has some days off and thought it would be good to send him to a library to write. I know in the writers career he gets a free one when he gets promoted but have some time until then. If they can travel are there any rules that go with that?
