My venue is in a pocket that has almost no cell phone access. Go a mile or two down the road and you're fine, though. How would you notify your guests? None of my guests have very small children at home, but several of them have children that are middle school age and above.
I could make a notation on the Wedding Website and if they don't read it then it's on them. I also need to mail cards to the guest that are attending so they can place it in their cars for free parking, so I could also include a notification there as well. Ideas?
Also, has anyone had to work with long range walkie talkies? Ideas on what to use?
