If our kids end up tiring out earlier than we think, is it okay to try to check-in for an ADR early to see if they will seat you? I guess the worst they could say is NO. I made one reservation that I am concerned about being too late but now there is nothing earlier to switch it to. I figure there are probably plenty of people showing up too late for their reservation so maybe it would balance out if I showed up early??? What do you think?
