I recently brought my v3 Pal Mickey in October this year. I will list the pros and cons I found with it.
Pros:
-Still works
-Tells you some interesting facts about the 4 parks
-Games and jokes help pass the time for lines
-You get CMs and other Pal Mickey owners smiling and striking up conversations with you
Now for the Cons:
-Some of it is outdated
-The "supposed" characters around you that Pal Mickey tells you about is nothing more than old character hangouts that aren't used much anymore
-Parades that it was suppose to tell you don't happen half the time. I was there for 9 days and only told me about a parade twice 30 mins before a parade
-It repeats the same facts over and over again if you return to the park multiple times I think I heard about the names on the windows on main st. about 15 times during my time there but I went to MK about 4 or 5 times
That was my experience with Pal Mickey. But if you asked me would I bring him back you bet I would.
Had people also smile at my Pal Mickey since on MNSSHP I had Mickey dressed in the Pirate outfit. During my trip to AK I had him dressed in his Safari outfit, other times I had him in the Pin Trading vest and pouch.
So he was still a ton of fun outside of some of the cons.
