Everything's better with Magitek
No, there's no dialogue at the Macalania travel agency. I need luck against Crawler (it's always taken quite a few tries on my test runs), so I don't want it in the same segment as Spherimorph. I didn't think about going back to the save point just before Spherimorph, though; I'll have to test that. However, if you can't get no encounters that way, then I'd bet it would be faster to save inside the travel agency.
