I'll be at WDW for the first week of June and I have yet to see the new queue additions except for in pictures. Keep in mind I'm trying to be unbiased about them until I get down there and check them out in person.
I have absolutely no problem with plussing the queues as long as they are done well enough to match the theme and overall feeling of "amusement". The only queue that had been touched when I was down there last was Space Mountain and I don't feel the games were implemented well, however it didn't ruin anything for me either. The line moved too fast when I was there so I never got to really play them anyway, which I felt was the problem. So I can take or leave those, BUT the overhaul of the queue itself was done amazingly well, so IMO those elements (lighting, rails, etc) made me quickly forget about the games which are obviously there to entertain the youngins.
The queue for Pooh (pardon the rhyme) looks fantastic in pictures! I really can't wait to see this one. However, I've read a few complaints that it is a noisy racket so I guess I'll have to judge that for myself. But again, they themed it well and outside of the "honey walls" didn't add any screens or super high tech items to take you "out of the Hundred Acre Woods". And I feel like the "honey walls" are a perfect blend of that tech because it'd be fun to touch a wall of honey, but... very messy. Ha.
The HM additions to the queue look a little cramped and the way they had tombstones in small planters of grass was absolutely ridiculous (I believe they fixed that anyway). However the look and feel of each "resting place" on their own look amazingly themed and fit the HM perfectly. The interactive elements I will not comment on until I see them, but the people going bonkers about seeing ghostly actions before you enter the house or seeing spirits before you get to Leota is just a tad over-dramatic to me. The attraction is called "Haunted Mansion". Therefore, you know it's haunted before you even get in line. To what extent is it haunted? That can be left to the imagination but the things I've heard of in the new graveyard are subtle and cheeky which I kind of like because it catches you off guard for the first eerie scene of the Ghost Host hanging from the ceiling. Again, I don't know how I'll feel when I'm there in person, but from what I've seen in pictures the themeing is there I just wish it was a little more spread out.
In regards to the possible PotC queue additions, I'm not sure what they are adding, but I hope it's done correctly. All the bickering about "ruining" it isn't going to stop them from "plussing" it so let's try and think of ways they could add something nice that would blend well. After reading everyone's comments, I started realizing something very ironic. Disney, known for wanting everyone to explore their imaginations, is kind of taking that away with some of these queue additions. And no other queue more than PotC got my gears turning. "What happened at this fort?", "Why were these guys (now skeletons) locked up?", "I wonder what these canons were used for.", etc. So long as they leave a few show pieces alone to wonder about instead of touching or reading about something I'll be alright. I personally think other than like 2 areas, the PotC queue is a bit boring. Adding more scenes to look at would help, but anything overly interactive and it may distract from the fort feel, but RUIN it? Hardly.
Sorry for the long post. I've kept quiet on the here for a while and felt like I needed to get some things out. Let's do all we can to just hope for the best on these new queues and remember that they are coming whether we like it or not.
