I was bored this morning so figured I'd bust out a Top 10 Best Category 8 Hotel list, especially now while they're pricing as Cat 7. And I also added a Worst 10 list, a warning to stay away from those redemptions.
Note: My methodology was to use the lowest average rate for a standard room as shown on Tripadvisor. The higher the lowest avg rate, the better the value; the lower the lowest avg rate, the worse the value. This seems to me a pretty good way of doing things as it's the base rate to enter the property. However, there are some instances where rates are really low in low season and really high in high season -- those are outliers that I'll list separately. I had the thought to average out a particular property's highest and lowest average rate for a standard room, (Tripadvisor gives a range of average rates for a standard room) but that's more work than I want to do without getting paid

. There are a few other property specific things that may work into an equation -- you'll just have to work all that out on your own.
