Our DS (well DW too) liked the Agent P adventure and eventually did all the missions over two days.
I love the concept, but hated the implementation. For one, all you hear now in WS is Dufenshmirtz's voice. Can the FONEs please come with a volume knob or headphone jack? Can they be disabled while in a restaraunt or while a show is performing? I also didn't like the go here, push here, go there routine. There were seemingly no 'clues' or anything to 'figure out', just go. And when lost, just look for a crowd of other agents crowded around place X, chances are that was your next stop.
Had it been a bit more of a scavenger hunt or a puzzle of some sort - I probably would have been more patient waiting for them to complete it. And while it should give you a chance to see parts of WS you might normally glaze over, most kids just are in a hurry to get to the next spot and never take in the 'meaning' or scenery that was laid out for you.
I thought you should be able to 'take out' other conspiring agents in some way, but DW said that was not very Disney of me.
Some of the 'reveals' were indeed kinda cool. Much better than the Sorcerer Cards over in MK, don't get me started on those.
Main point, is if you are a touring plan, on a schedule type of person. Be prepared to let all that go while in WS listening to your FONE.
At least with Kidcot stuff and Passport, you get to meet real people from their home countries.
