On PE: Swan is the only 4.5* resort with a mandatory fee. (The other 2 4.5* resorts are GF and AK Jambo.)
They normally round the number of reviews on PE deals down to the nearest 100 (or 10 if less than 100), so I'd expect to see the deal list the number of reviews as "400".
The deal said that exact number 445? Weird. Could you tell me the date are you looking at?
I have not looked at Hotwire deals much myself, but regarding the 0.2 from AK: The only 4* resort that close are the AKL resorts.
Here's a map of all resorts in BC and DS I made for a visual:

Curious, Anyone know if the distance listed on a Hotwire deal is accurate?
