The Seas is a C-Ticket (nice, yeah, but not special) that replaced an other attraction. It also has been open for 5-6 months now.
Nemo: The Musical is absolutely an E-Ticket caliber show. Great addition, no doubt. Makes DAK better all the time.
Laugh Floor is a troubled, misplaced attraction that won't open before late April right now. It is also in no way a major attraction.
Dream Along With Mickey is a slightly improved version of the same castle drivel we've had for years at the MK. Fresh? Slightly.
If I'm not mistaken, the rest of what you list are very minor entertainment offereings, mostly west coast based.
Pirates and Princess Parties are an extra cost. They appear to be well done. But since the regular guest has to pay another $40 to attend, you can't place them into this.
