A time-share plan may be created in any accommodation unless otherwise prohibited. All time-share plans shall maintain a one-to-one purchaser to accommodation ratio, which means the ratio of the number of purchasers eligible to use the accommodations of a time-share plan on a given night to the number of accommodations available for use within the plan on that night, such that the total number of purchasers eligible to use the accommodations of the time-share plan during a given calendar year never exceeds the total number of accommodations available for use in the time-share plan during that year. For purposes of the calculation under this section, each purchaser must be counted at least once, and no individual accommodation may be counted more than 365 times per calendar year or more than 366 times per leap year. A purchaser who is delinquent in the payment of time-share plan assessments shall continue to be considered eligible to use the accommodations of the time-share plan for purposes of calculating the one-to-one purchaser to accommodation ratio.
