Like all timeshares there is no real value except in winter weeks.
At Belair that would be 51 52-53 and weeks 1-13.
Otherwise you can always get a unit for the maintenance fee or less.
The assessment has owners threatening to sell but there really is no value for most.
There are a large amount of unsold units given back to Belair.
Suspect the assessment is mostly to cover that loss of income but sure they will sugarcoat the truth.
