Which leads to the follow up question: if you travel far enough in one direction do you end up where you started? (well, no, not if space expands faster than c).

If it wasn't for the expansion, and if the universe had positive curvature, then yes.

As it stands, there's not only the expansion, but the universe also seems to be flat -- meaning it's spatially infinite, not just borderless. That observation is also compatible with a very, very small curvature, but in that case the size would still be so large that it wouldn't be practically possible to circumnavigate even if it wasn't expanding.
