Anyway, there was no map, street address, or directions on the invitation or the wedding Web site. The park and lodge don't appear accurately on many online maps, and it's outside cellular and GPS range. I was able to find it OK because I live in Mudville, but some of the out-of-town guests were confused and arrived late.
This would be indicators to the hosts that they DO need to put some sort of assisting information.
But just putting the street address wouldn't help, because you said they don't appear accurately on many online maps. They'd need to put directions.
However, being local, it may never have occurred to them that it was outside cellular and GPS range; or that it didn't appear accurately on GPS.
It didn't help that the Beaver Park Lodge was indeed in a park, just not Beaver Park. The park that the lodge turned out to be in had a different but similar name. I'll call it Beaver Pond Park (just to be a little bit silly).
Near the street address given by the lodge's Web site, which linked to a Google map utility that showed the street address, there was a neighborhood called Beaver Park. It had nothing resembling a lodge or wedding venue. Unless people knew to go to Beaver Pond Park five miles farther down the road on the other side of the mountain, they would never have found the lodge. Second-guessing the lodge's own Web site would not have been obvious.
Four or five couples arrived fifteen to thirty minutes after the scheduled start of the ceremony, but since the ceremony was delayed they didn't miss it. A few other families trickled in during or after the ceremony, although they stood in the back so as to not disrupt the proceedings and didn't take a seat until after the ceremony was over. Some missed the whole ceremony. I won't go on the record as saying they got lost, but about a quarter of the guest list (all out-of-towners) arrived at least a quarter of an hour after the ceremony was scheduled to begin.
