Adam in flights 1 & 2 we played in around 4.5 hours each day. We teed off at 9:12 on Tuesday and Wednesday (so we were close to the end of the field) and still got done in 4.5 hours. Which considering Wednesday we played cart paths only at Caledonia is kind of amazing.
We really did not see any “back-ups” during our round.
I still think tee times are the better way to go, we played in two shotgun starts this week after Myrtle Beach and the time to pay was about the same but we ran into more back ups. I still think the biggest benefit is you can show up go to the range and you do not have to fight for space.
