Some other factors I wonder about the status of people's reviews:
People may only feel inclined to write if they personally had a bad or awesome experience, very little middle ground. So they accounts for some of the negative reviews.
There are likely a number of people who go that may prefer to camp, stay in B&B's or rent self catering, so perhaps they are disappointed when they feel they are paying so much and then get the experience they offer at the Disney resorts.
And also, the hotels are of a smaller scale with lesser service than the US Disney resorts.
All of these may be contributory factors.
Since 1992, we have stayed in the Santa Fe about 9 times or so, Cheyenne a couple, Sequoia Lodge about 7 or so, NBC about 3, HNY 9 or so times, and the DLH 3 times. Of those, the visits have varied. The worst experiences have been in the NBC and HNY (though the HNY used to offer some of the best). The best experiences have been at the DLH, SL and the value resorts.
So price point is not always relational.
I have had excellent stays at the DLH, but their prices are rediculous without discounts (and even then questionable).
Now, whenever possible, we opt to stay at MArriott as we have a better overall experience. I would stay at the DLH again, and we may take the kids for fun to the Cheyenne some time.
But DLP does have quite a bit of room for improvement in the hotels, which is a shame as they have been so good in the past.
