We're taking our first big trip with the grown kids and grandkids this summer. DH and I love ROR and want the 'kids' to experience it. Is it possible for the 4 'kids' to ride while DH and I are on line/waiting with the 4 toddlers, and then for us to hand the toddlers back to their parents so that we can ride? We're planning on early entry with no genie+ or LL.
