I couple years ago I read a report were various (color, BxW, transparency) rolls of film were subjected to different temperatures for various amounts of time. I can't find the article but I came a away with the realization that film is most more hardy and resistant to heat than I thought. The other points I remember was store in original packs until shooting and return to plastic cans (35mm) or similar for larger sizes. Also fresh film withstands heat than out of date film. It takes a lot of heat (100 degrees F) for a long times (days) to really cause troubles. You are OK.
