What, no going to the parks on your arrival day? What are you thinking? We typically arrive mid to late afternoon (between 2 and 4) after about a 9 1/2 hour drive, and by the time we get there, we are so ready to go to the parks that staying by the pool or just visiting DTD wouldn't suffice! If I told the kids we couldn't go to the MK until the next day, I would be killed! Seriously though, we're all ready to get to the parks and enjoy some of that Disney fun as soon as we arrive, no waiting for us. Picture this: this July I went to bed on Saturday morning at 1 AM, got up at 2:30 to start driving, had made it to Disney by around 2 PM, unpacked, got situated, were on a bus with the wife and kids by 3:30 to the MK, and stayed there until 10:30 to see the parade and fireworks. We made it in bed by 11:30. Now that's a first day! But we wouldn't have it any other way. Of course, we all had UPH passes, so it wasn't like we were "wasting" a day, which I guess you might have to consider if you only had Plus passes, but I can't imaging not setting foot in the MK on your first day!
