What is the difference between a condominium hotel and a time-share?

The difference is in the ownership of the property. Read your governing documents to determine if time-share use is permitted by owners. The definition for a hotel implies irregular lengths of stay, as does time-share.

The difference is in who owns the unit. A condominium unit owner may not be able to use the unit as a time-share unit; whereas a hotel unit can be used for irregular lengths of stay.
