I found a possible typo in the code that was causing a really thin column for the venue info, then the map on the right further over.
In line 316 of the-events-calendar/resources/events.css you have the following:
#tribe-events-event-meta .column-location {
If you change that to:
#tribe-events-event-meta .column-location {
It will then give you full width of your information, instead of a narrow little column.
This may not be a typo, but thatought I’d report it, in case anybody else is having trouble.
