I agree. US is smaller, there are fewer choices and requires a lot less planning. Do NOT confuse this with inferior - on the contrary - I think US is AWESOME and thanks to US and especially HP - WDW has had to get off its butt!!!
I also find that a lot of the questions asked on the WDW side are a little, well how do I put this nicely - I bit "specific". The questions are so specific and it seems like WDW may be the first time a lot of people are using it as their "first foray into traveling" - which is fine - and love the fact the forum is here to answer those questions.
I do however wish that there was a bit more activity in the US area as the parks really are worth visiting!!
