Not sure what exactly you're asking...but the main advantage of having a trust is that you avoid probate. Since the property is in Florida, then if you die without having the property in the trust, then probate will have to take place in Florida. If you have
DVC property owned by the trust, then your survivors can avoid all of that. Also, probate is public record. Trust transfers are not.
If you already have a trust, then you would add your DVC property into the trust for all of the same reasons you had the trust in the first place. If you want anything more specific than that, you should probably talk to your personal attorney and/or financial adviser.
