It doesn't matter "who" was in the unit nor whose credit card was used. The agreement is between DVC and the member for the use of a unit. Any outstanding issues or problems are the responsibility of the owner to have addressed. Disney did not rent to the person in the unit, they rented to the owner and clearly established the rules for use of the unit. A court probably would not force the member to pay the bill but they would uphold DVC's right to deny use of membership until the bill was paid. Denial of use when monies are owed is clearly stated.
While it is would require an extreme circumstance, members should keep in mind that a renters behavior could even forfeit your membership. There's a whole list of rules including using the units for illegal activity (i.e., selling drugs), having firearms on property or even a case of losing one's temper and getting into a physical fight. If someone you allowed to use your unit were arrested while on property, you could be subject to losing your membership.
Disney holds the units in trust for everyone's use and has rules in place to help protect themselves and other members.
