Marceline's used to be able to cut them up, but the stopped doing it about a year ago. You might be able to get a rogue employee there to do it, but not likely. I'd suggest getting a knife from your hotel.

I'm glad you posted about this, as this was what I thought was the case too. I thought I had recalled reading a while back that all of the various candy shop CMs stopped cutting up the apples for guests, but I wasn't sure if it was still the case.
I had to giggle at the "rogue employee" reference -- for some reason that struck me as funny (I have the image of an employee sneakily cutting up apples for guests behind the scenes, when no one is looking!

).
Sherry - I obviously did miss it. No problems though. I am giving my DD the link to this thread and she has all day Monday to read up and plan. That is one of the main reasons why I decided to tell her on Sunday. She likes to research and plan and is much better at it than I am. In fact, this is one of the first times in about 6 years that I've purchased the airfare, made hotel reservations, etc. She usually is in charge of things like that and I am just, "Mom! Wallet!"

I actually prefer it that way.

You seem to have a great attitude about it!
I hope your daughter enjoys reading through the thread and planning everything out. As I mentioned a few days ago, I, too, used to read the Birnbaum guides back in the '80s and early '90s (I would always buy the updated versions), so I know how fun those can be! I would absorb every bit of information from them!
I got myself confused...I remember reading the Blog article, but for some reason I thought that there might be some changes to how the Villains meet and greet occurred, but I think the "something new" header was only for the "Mystic Magic Show". So, unless they tweek something inside (maybe some new decor or things in different places) it sounds like it'll the same as the last few years.
In terms of the Halloween Carnival, I think they might have a treat trail in the general area (Big Thunder Ranch), but I'm pretty sure the Carnival area is closed off. At least, I'm pretty sure that when I wandered by there one night (after the listed hours ended), the gates into the actual Carnival area were closed.
The Carnival is closed for the MHP (or was closed up until last year), and all of the Carnival entertainment shuts down, as I mentioned.
The reason I said that "there may or may not even be a couple of treat stations in the area" (depending on whether or not that changes this year) is because the Carnival and the Roundup are right next to each other and literally transition into each other. It's all the same general area (the Carnival/Roundup/Ranch), so I think that once people get to the actual treat trail they won't know whether they are in the Carnival or the Roundup, really. But, yes, technically, the treat trail will probably not be inside the actual Carnival portion of the area.
