I know that you believe that you are correct, but you are not. Disney knows that folks paid for tickets that last until 7 PM and allows guests to use the park, and that means get in lines, have dinner and shop until 7 PM> Now when the clocks strikes 7, entry is closed.
Again, you may think this is the correct plan for everyone to follow, but unless Disney agrees.....you are just suggestions. Now....what time can you enter the MK if you have a party ticket? The party starts at 7PM, but Disney allows folks to enter at 4PM. They are allowed to secure FP for those three hours between 4 and 7. Pretty nice strategy for party goers, right? Pay for a party, get three additional hours and have FP the those folks who paid entry to the park that day might have wanted. Or is this bad manners?
You see, you cannot have it both ways. Party people have the ability to enter at 4, use the shops, restaurants and get their meals our of the way before the party starts, and book FP for the attractions that they do not want to stand in a line for. The folks who paid for those park tickets are sharing the park fm 4 to 7 with a lot of people whose tickets are nto actually valid until 7, and I have never read one complaint about that. So if we follow YOUR unles...Party people: your time starts at 7PM. Not one second prior..... So it is your responsibility to make your way in at 7, and stay off of the attractions and out of the restaurants so that the peopl who paid for those things can enjoy them without having to fight for ADR's and places in line.
