I would have to say I am of a different opinion than most here. I see absolutely nothing wrong with having a waiter at the entrance gates (rides is a different matter unless of course it is that someone ran to the bathroom, etc...). For example, I always go wait out at the security entrance at least a 1/2 hour or an hour before they even open the esplanade, and then am always first to one of the entrance gates, and wait there for an hour. Usually 20 minutes or so before the gates open my wife and 2 very young children join me in line. Their patience level would not last for much longer than 20 minutes and would be a much greater disruption to the line if they were with me the whole time. I tend to actually talk to the people in line behind me though, so they know my family is coming (I am not even a talkative guy normally, but there is just something about the excitement
Disneyland brings that gets me chatting about rides, parades, etc...). I wouldn't care if anyone was upset either though, because, come on, you're at Disneyland the happiest place on earth are you really going to start you're day off grumpy because a father got up 2 hours early to get into the park first for his family, while maintaining a happy family. Besides, there is too much judgment in this world. You never know why a family might do this strategy. Perhaps the kids have disabilities that aren't apparent to you and their kid can't wait in lines. Perhaps that is just the culture from where that family comes from. Basically, I think it is up to each individual family to craft their entrance strategy to what works for that family. Of course, I am typically a pretty laid back easy going guy (got that growing up in Oklahoma I guess), and there really isn't a point in allowing someone else to determine what your attitude is going to be, especially when you're on an awesome Disney vacation! Too much to be excited about and to do! So sorry if I am ever "that guy" in front of you who stood in line up to 2 hours before the park opened by myself (yes I know that is weird to many, but that is what I enjoy doing at Disneyland) and my family shows up in rented strollers 15-20 minutes before the gates open (I always stand first in line and ensure that there is plenty of room for my wife and kids to show up) and you get grumpy, but Grumpy only belongs in Snow White's ride and on T-shirts, hats, and sweaters at Disneyland!
