The guidebook changes all the time, @Janet889 , but I do remember a workaround from awhile ago.
Try inputting just the street address as the place name, add a little information, and save. Then go back and edit it to reflect the place name, add the rest of the information, and save.
Apologies if this doesn't work these days. It did once upon a time.
Hi @Janet889 , was wondering if you ever found a way around this? I have the same question! There is a local spot near me that I know would interest guests but am unable to add it.
