Honestly, we didn't do HOURS worth of photos after the ceremony. I think it was only about an hour. We are on a more strict schedule at Las Caletas, but I was more than happy with the amount of photos we received from that time period.
I guess that aspect comes down to personal preference. If I told my DH that we would be doing photos for 2 hours after the ceremony, I think I would have been alone in most of the shots. No way I could get him to be that patient. I don't think I could have been that patient either, considering we took pics for about an hour before the ceremony as well. We photographed separately prior to the ceremony so our only shots together were after.
