I agree. The only reason WDW can charge the prices they do for their rooms is because of the proximity to the parks.
It would be like staying at a beach resort and never going near the ocean, or going to a ski resort and never hitting the slopes. That is not to say that there are not other things for people to do at those resorts, but it would be hard to keep busy for a whole week doing them. It would also, IMO, be a waste of money. See above, and make a substitution.
As mentioned, it is only a choice if the family doesn't mind splitting up for the whole day, or you have lots of money to spend. I would have a hard time justifying paying for both golf fees AND park tickets on a daily basis, not to mention meals, etc. but that's just me.
As mentioned, someone may be there for a convention, and is at meetings all day (my husband has done this in the past; we stayed at the Polynesian and park hopped while he caught a shuttle downtown) but even then he stayed an extra day to hit the parks. :lol:
