I just have one question for all the "rules are rules" people. Have you ever driven 2 miles an hour over the speed limit, stayed over the parking limit by just 1 minute, had 16 items in the 15 item or less line(that includes that pack of gum you toss on at the last second). come on "people in glass houses"
Got a ticket for speeding, got a ticket for parking too long (never had a parking ticket on my windshield so thought we made it back in time unitl months later when we got a "second notice" about it), and I have NEVER stood in an express line with anything over the number that they said. Not even multiples of the same item; when I'm behind someone whose stuff is being counted, I'm waiting longer than if they only had ONE of those yogurts instead of 20, so I don't do it to those behind me.
Then again, glass houses don't apply to me since I'm not JUDGING, only telling someone who ASKED "Would it really be that bad to lie for one night?". (though I also freely admit that I do judge on some things, as I am sure others judge me!)
I am VERY much a "worse case scenario" person, and even have a book with that name, LOL. If I did it, and something were to happen and they were to find out that my 4 year old was in there on a lie, and that caused some sort of care to NOT BE PAID FOR (say they fall while not being supervised, and normally their insurance would kick in, but it wouldn't b/c I had lied to get my 4 year old in there), that would be awful for soooooo many reasons. An accident would be bad, but if it's going to happen it will happen, and if you end up paying 1000s on the care for YEARS, it reminds you of the awfulness every single month, and would remind you of the age lie every time.
I wouldn't do it, no way no how.
We went twice when DS was free, and when he turned 3 we were happy to buy him a ticket (and upgrade to AP), and while I'm sure we'll plan a trip right before his last "child ticket" birthday, that will be totally legal and aboveboard to do it, and we will be happy as can be to buy his "adult" ticket!
Don't do it. The "what ifs", even if only financial, are too high.
