It appears someone in theat piror post confused that the unit's being declared to be a commercial unit in the BLT condominium meant the unit was part of the common elements. That is not correct. Any commercial unit that is part of the condominium is, by definition of a "commercial unit," not a common element.
It thus does not resolve the issue of whether Disney can treat TOTWL as a incidental benefit that it can exclude resale purchasers from using. Resale purchasers can be excluded from the use of an incidental benefit, while other members can use it, only if the annual dues to which the resale purchasers contribute are not used to maintain, repair, or operate the applicable incidental benefit. The documents declare that the owner of a commercial unit (which was DVD unless it sold or transfered it to another Disney entity) covers all of ithe operations, repair, and maintenance costs of a commercial unit. However, there could be things in the commercial unit, such as bathrooms, declared to be common elements, or more particularly "limited common elements" usable when using a commercial unit, and the association (and thus owners dues) is responsible for the mainrtrenance of those common elements. Thus, you get into a more complex analysis to determine whether, and the extent to which, resale purchasers can be excluded.
