We are letting our boys go in DQ alone our next trip (12 & 14) while we go to PI we have let them be on their own in DQ before, but we were in the building up where the Cheesecake factory is. We gave them a cell phone and call and check on them. Next trip we will watch them go in, they have to stay together including restroom breaks, they must not leave the building until we call and tell them when we are waiting at the exit. We will only be leaving them for 2 hrs.
