I don't think it's a good idea because someone would try to make it into a 48 hour marathon. LOL. I already see people who show up on open and try to make it all the way to close and thats where you see people with glazed eyes or sleeping in strange places. The buses at close are always filled with such happy looking people,LOL.
I do open to close, full days quite often, and never have glazed eyes, need to fall asleep, or look unhappy at the end of the day! In fact, I traditionally linger on Main Street for at least an hour (maybe more) after the official closing, enjoying ice cream or a popcorn, the Castle "Kiss Goodnight" presentation, the music loop, and just the overall Magical atmosphere. As long as I have between 6-8 hours of sleep the night before, I'm good! And once you get used to the 17 hour MK days during "high season", the more standard 12 hour days that are the longest session offered by most parks in the country seem like nothing!
It's just that my favorite time in the parks are the last few hours before closing, for the nightime magic, parades, fireworks, and late night walk-ons. But I ALSO LOVE the first few hours where you get the Welcome Show, the rope drop, and the excitement of seeing the park come to life and surfing a wave of walk-ons before it fills up.
And once I'm there, I NEVER want to leave! I can count the amount of times I've left a theme park before it closed on the fingers of one hand! Not just at WDW, but at ANY park. And that was usually for a really important reason where I knew beforehand I'd be leaving early, such as to watch a New Orleans Saints playoff game!
So if I don't want to miss the beginning or end of the day, that leaves just skipping the middle to take a nap. Except I'm so excited to be in the park, I never feel like I need one! So why leave PARADISE?!
Another thing is, I like every attraction in all 4 parks except Laugh Floor enough to do regularly, but if I only did partial days, I'd be tempted to always do my favorites, so my "second tier" of attractions that I have time for on full days would always get skipped. I notice this phenomenom whenever I park hop to the MK after a full day at AK and only have time for a few hours worth of attractions before closing. I always seem to gravitate towards the same favorites in these cases - the Fantasyland attractions, the coasters, Splash Mountain, the Country Bears, and a few others.
Full days allow me to experience a
complete park, sequentially by land, and experience it like the true complete work of Art that it is! I liken it to listening to a complete album, as opposed to listening to highlights of it via favorite tracks.
PS. I'd LOVE to try the 48 hour marathon! Or at least a 24 hour one!
