Just got back and used the MM the whole time I was there.
I loved the fact that you could be standing at one end of the park and see what the rides were doing at the other side....helps with running back and forth. The times were always right on, no problems there.
I did not use the character feature, so I can't comment on that.
Some of the things I thought needed improvements on:
1. When I would go to the "List attractions with wait times under 30 minutes" it would not always list ALL the ones that were under 30 minutes. There were a few times that in the list it would show 5 or 10 minutes and then when I would bring up the specific 30 minutes or less, it would not show that attraction???
2. I have a LG chocolate touch, which has a smaller screen. I found it hard to scroll through the list of attractions. It would take a steady hand to get to the one you wanted.
3. Not a big deal, but the weather listed for the day was inaccurate. It would say rain only at 4pm almost every day....and yet it would be raining all day long some days and it would show it being sunny?
I would still recommend it for anyone traveling to Disney; it was well worth the $10.
