My inlaws have a reservation at boardwalk June 20-July 3. They're looking to extend their stay to July 6. They're staying in a studio. Is there any availabilty during that time?
Do you mean they have a DVC reservation? If so, they, or the owner if it is not them, needs to call and find out if additonal days are available. Likely not for that time of year but won't know until the call is made.
